Introduction
Hello everyone this is Fernaldy from Indonesia, I played the yellow purple Mastemon deck at Digimon TCG Indonesia regional tournament. Why do I play Mastemon… Before the tournament I didn’t have many options, it’s either Mastemon or yellow hybrid security control. At the end I choose Mastemon over yellow hybrid because the deck is more versatile, it has multiple ways to destroy both Digimons and tamers and also minus DP and "SecurityAttack-" to opponent Digimon.
With the new Meiko, Meicoomon, and Maycrackmon in BT9, it adds more consistency to the deck because Meiko provides an early game set up for hand and trash with additional memory plus on play for double color Digimon such as ST10 Tailmon and BT8 BlackGatomon to close the game. The game plan is to set up and control the opponent board with many ways of free summoning from security and many destroyers to clear up opponent Digimons and tamers.



Deck's Distribution
Digitama: 4 Demimeramon
Best digitama for purple so far in the game, draw 1 and discard 1 to refresh hand and set up trash.
Rookie: 4 Tapirmon
I play 4 Tapirmon for the rookies because Tapirmon provides an extra 1 draw and in practice and testing. I don’t have many chances to build up from rookie to ultimate so I prefer to hard play the champion and the ultimate so the purpose of Tapirmon is only to provide early aggro and an extra draw
Champion: 4 Tailmon, 3 Meicoomon, 1 BlackGatomon
4 Tailmon are the best cards of the deck providing 2 card search and minus digivolution cost with end turn Jogress (DNA digivolution), the main engine of the deck. Meicoomon is a security Digimon that can play for free and is also a good target for Maycrackmon to discard and Mastemon could put her into the security and play other Digimon. BlackGatomon BT8 is the finisher of the deck most of the time I end the game with it.


Ultimate: 2 Lucemon FM, 3 LadyDevimon BT3, 3 Angewomon ST10, 3 Maycrackmon, 2 Holyangemon BT1.
The ultimate lineup is the usual composition for the mastemon deck. LucemonFM main target to summon from Mastemon providing destroy a lvl 6 or lower Digimon or tamer, LadyDevimon for the extra draw and discard to set up hand and trash, ST10 Angewomon is a great card give "SecurityAttack-" and very helpful against OTK decks such as Alphamon and Grandiskuwagamon, Maycrackmon also a great card against the rookie rush deck and Armor Rush deck because the minus DP and destroy, BT1 HolyAngemon for the extra recovery.
Mega: 4 Mastemon ST10, 1 Ophanimon FM, 4 Zward Defeat
I play 4 ST10 Mastemon because it is the main card of the deck. It can put 1 LVL 5 or lower yellow/purple Digimon to security play LVL 5 or lower yellow/purple Digimon from security, and destroy opponent Digimon when a Digimon played by effect with lvl equal or lower from the played Digimon. So basically we get a free LVL 5 or lower Digimon summoned and 1 additional destroy [once per turn] every time a Digimon played by effect. This effect also synchronises with Digimon that could be played from security such as Meicoomon and Omnimon Zward Defeat and destroy opponent Digimon on both turns. Ophanimon FM is an additional mega to give recovery, destroy and summon LVL 4 or lower from trash
Omnimon Zward Defeat is the best card to play from security as a big body on the field with 13K DP and destroy 1 Digimon when destroyed and also destroy opponent tamer when evolving with 3 costs to choke memory

Tamer: 4 Meiko, 2 BT1 TK Takeru
4 Meiko is the main engine of the deck to search for Digimon and set up trash and additional memory plus on "both turns" whenever a double color yellow/purple played. 2 BT1 TK Takeru for memory fixer and saving important card in security and replace it with another card usually for Tailmon ST10 and Mastemon ST10.
Option: 3 Purple Memory Boost, 1 Reinforce Memory Boost, 4 Flame Hellsycthe and 2 ChaosDegrade.
Purple memory boost is for early gameplay to search purple Digimon and give extra 2 memory in the next turn is very useful because in this deck we have a big memory cost to play our Digimon. Same goes to Reinforce Memory Boost, it gives extra 3 memory, 1 recovery, and 1 card to hand.
Flame hellscythe is the best option in the game -6000 DP to opponent Digimon and play DP 6000 or lower Digimon from trash most of this deck LVL 5 has 6000 DP, so it’s very versatile and combine with Meiko if we play Maycrackmon from the trash, we can have memory plus and also extra minus DP
ChaosDegrade the best removal in the game but it has a big cost, there is no solution to counter this card except for Kongou or A Delicate Plan.


Tournament Report
Format: Swiss Round BO1, Top 4 Single Elim BO3
W: Win, L: Lose, D: Draw
Round 1 VS Grandiskuwagamon (L)
One of the best decks in the meta with a strong chance to OTK with multiple security plus and finish with Mimi to move Digimon from the hatching area. I open with a kinda brick hand and I should have mulligan but I want to save Tapirmon and Mastemon in my hand so I decided not to mulligan. But too bad that I didn’t have any Digimon to play after evolving to Tapirmon so I pass a turn giving him 3 memory and play a Tailmon in the next turn but he has x antibody tamer and Okuwamon X to rest Tailmon and destroy it, and I get OTKed in the next turn.
Round 2 VS Grandiskuwagamon (W)
Pair up with another grandiskuwagamon deck but have much better set up this time. I set up a Takeru and 2 Meiko, my opponent cant finish the game on the first attack, and Omnimon Zward D pop out from security so I could hit Grandis and Jogress to recovery. Controlling the field and finish with BlackGatomon.
Round 3 VS Yellow hybrid (W)
A good matchup for Mastemon because I can destroy tamer and yellow hybrid a slow and more defensive deck in this meta ultimate fusion got banned so really lacks the firepower from Susanoo. My opponent goes first and plays Takeru so I play tailmon ST10 in the second turn he plays Takeru again allowing me to set up Takeru and my tailmon ST10 survives in front and he evolves TK Takeru into a hybrid and makes Jetsylphy to recover 1. And then I jogress with Angewomon destroying Jetsylphy and another Takeru and keep pushing the game with "securityAttack + 1" finish the round with Tapirmon and blackGatomon rush.
Round 3 VS Imperial jogress (W)
Didn’t expect to meet Imperialdramon deck in the tournament, going first I play Tailmon ST10 giving him 5 memory to search both Angewomon ST10 and Ladydevimon BT3. Somehow he didn’t have rookie so he play Stingmon in front and evolve into Paildramon giving me 3 memory and I Jogress (DNA) into a Mastemon, destroy his Paildramon and keep control the field and push the game.
Round 5 VS Alphamon (W)
Finally, I meet the most used deck in the meta, my hand was not the best but I still can make up for the early game. My Tapirmon hit his security but not destroyed 3x hitting Ryudamon. But my opponent successfully made Alphamon Oryuken and hit 4 security and play Kongou so I could not finish the game with Tapirmon. Then I play ST10 Angewomon to "securityAttack-2" into his Alphamon Oryuken giving him 4 memory then he pops memory boost to make it 6 memory, drop 2 Musha Yuji, hit security and put Dorugreymon into Alphamon Oryuken digivolution source make it "securityAttack+2", hitting a Meicoomon in the security, it is free summoned and I tap Meiko to "memory + 1" and then Alphamon Ouryuken actives again with the effect of Oryumon and activates removing source to gain memory, he removes Oryumon and attack again and tap Yuji to put another Oryumon in his source, but it hits a Flame Hellscythe and I play Holyangemon BT1 from trash recovery 1 so he couldn’t finish the game
Top 4 VS Grandiskuwagamon (W)
Game 1: in top 4 I meet the same opponent from round 1 who played Grandiskuwagamon, I go second and play Takeru and Meiko. Fortunately, he didn’t have the Grandiskuwagamon and I could play Tailmon ST10 and Jogress (DNA digivolution) destroy all of his Digimon in front and keep pressure and controlling his field
Game 2: I have probably one of the best set up in the entire tournament by opening 3 Meiko in the early game but my opponent also had a great setup and could hit 3 security early, and I make a big misplay here I thought I have the Mastemon in hand but I didn’t I should have finished the game with Mastemon summon BlackGatomon but I don’t have it so I evolve into Ophanimon FM and recovery+1, but my opponent just make another Grandis and finish me.
Game 3: Standard early game both for me and my opponent but he misses one of his LVL 5 and I play maycrackmon to destroy his weedmon and rookie in front putting pressure by an early attack from tapirmon, accidentally when he shuffles my security he opens 1 of the card and it was meicoomon so he didn’t hit all the security and leaving maycrackmon on the field because he has the piercing if he hit then meicoomon could play on security and finish him. So I evolve tapirmon into tailmon ST10 and jogress to destroy both Grandis and blocker and win from that.
Final VS Metalgarurumon X (W)
Game 1: my opponent didn’t have the perfect evolution he put some Digimon in front to search for the missing piece so I have the time to jogress even though I didn’t have any tamer to play but still successful in jogress and keep pressure but metalgaruru also can board wipe pretty well by bounce opponent Digimon so I make a backup plan by evolving tapirmon to tailmon ST10 at hatching area to counter his metalgaruru x antibody in front, and he makes another evolution line but unfortunately the last attack he open Omnimon Zward D and ChaosDegrade and I win the game.
Game 2: I go first and play the usual tamer and memory boost gameplay but this time my opponent had a better evolution line and put big pressure on me and clear all my security fast and I couldn’t make a comeback
Game 3: I didn’t have the best opening hand and just play Takeru and Meiko from hand and set up my trash and hand, my opponent then try to finish me so he attack with Weregaruru x antibody with "SecurityAttack+ 1" and 2 rookies. Fortunately, I open Flame Hellscythe in my security minus 6000 into Weregarurumon and summon a Maycrackmon, discarding Meicoomon then minus another 3000 into Weregarurumon x and destroy one of his rookies after that I control the field comfortably. he still manages to board wiped me but I can counter board wipe again and finish the game with blackGatomon.
Conclusion:
I am very satisfied with the result and the consistency of my deck even though I still think Mastemon is still not a tier 1 deck because of relying on security with free summon and option. But the power to board wiping opponent Digimon and tamer is still a strong strategy and very strong control but needs a perfect tempo and right decision. I think Mastemon is a high-risk deck if you make a wrong play or decision it could cost u much because of the big memory you give to the opponent.
Mastemon deck is very fun to play with a variety of Digimon and options, I consider a couple of cards into my deck such as Gazimon into my rookie lineup to counter-memory plus from my opponent but I think Tapirmon is better for early consistency and draw we could also put Neodevimon to counter tamer play, Ordinemon, Hikari BT8, Takeru & Hikari BT8. I also hope for double color yellow and purple tamer in the future that could boost the deck
I want to thank all the organizers for running the tournament well, I hope with an event like this we could improve our DCG community in Indonesia, and shoutout to my friends and community Ogre Citra card shop and hobbies.

Regarding BT8/EX02 meta, do you think cards like Creepymon and Avengekidmon are useful and necessary due to Yellow hybrid and the mirror match. They are so long a drawn out, I’m wondering if it’s absolutely necessary to play those cards or is there a way to navigate those matchups where I should need them before decking out, or trying deck them out. How would you have considered playing the deck in the BT8/Ex02 meta?
Hi , i think you can splash both avengekid and creepymon into the deck but not really necessary and i don’t think both of the card can make the deck better. But both of them still a good splash in some situations.
Regarding BT8/Ex2 meta back in the days i didn’t play mastemon at all cuz meiko have not released yet so it’s really hard to play at early game and D reaper was so popular and i think i didn’t stand a chance to win against them.
But to play in BT8/Ex2 meta you can boost the consistency by adding more rookie and play yellow double tamer from BT6 and play 2-3 ophanimon. To counter yellow hybrid i think you should just need to control their tamer early and put early pressure and for mirror just wait your opponent to summon 1st and counter it
Thank you! Makes sense!
