How to play D-Reaper

EX-02 introduces a brand new engine in D-Reaper, which may appear a bit overwhelming in the beginning. We take a deeper look at this engine with hopes of demystifying the strength of a D-Reaper deck!


EX-02 celebrates the 20th anniversary of Digimon Tamers, which is the 3rd instalment of the anime series released in 2001. D-Reaper is the main antagonist, an anti-virus program and is not officially recognised as being a Digimon.

D-Reaper utilizes a variety of extensions, or forms known as ADRs (Agents of D-Reaper) to perform it's bidding. There are 9 ADRs in total, each having its unique codename and purpose. This is similarly realised in the modern Digimon Card Game. 

This analysis will be based on what we know so far, since at this time of writing, only 5/9 of the ADRs, in addition to its Digitama and the main Reaper, were revealed. 

[EX2-007] Mother D-Reaper is, despite its huge 15000 DP, a Digitama. It is unable to attack, and cannot be affected by your opponent's effects therefore cannot be suspended, returned or deleted conventionally. The only probable way to remove this Digimon would be to attack it while unsuspended, which is no easy feat due to its massive DP.

Meanwhile, [EX2-055] Reaper can be played for free by trashing 7 Searchers from Mother, and will be able to attack multiple times on the turn it is played. 

So the engine is actually quite straightforward: grow Mother D-Reaper by putting a ADR-02=Searcher from play or hand to the bottom of its digivolution cards once every turn, and play a Reaper once Mother has 7 digivolution cards.

At a minimum, Reaper would be able to attack 4 times for having 7 Searchers in trash, but it should not be difficult to setup another Searcher in your trash for 5 hits, which is pretty much an endgame play. However, how long do we need to setup Mother's 7 digivolution cards for that to happen?


With sheer importance of [EX2-046] ARD-02=Searcher should be clear by now, and fortunately he does not have a 4-card limit in your deck. 

Searcher also has a very low play cost of 1 when you do not have another Searcher in play, which should be an easy condition given that Mother will be there to absorb a Searcher each turn. In addition, there should be no worry about a depleting hand size thanks to Searcher's [On Play] effect. 

However, fact remains that it would take at least 7 turns to setup your Mother D-Reaper, and a 7-turn timer may be too long in this meta. So how can D-Reaper slow down the game?

ARD-01=Juri, The Accelerator

[EX2-049] ARD-01=Juri will accelerate Mother's timer. My suspending this Digimon, the player can put a Searcher (revealed from top-5 cards of deck) to Mother's digivolution cards. This is a Digimon that your opponent will want to remove immediately, and should be a very simple feat given that she has only 5000 DP and will likely be suspended during your opponent's turn.

Other ARDs: Building Tempo

Other revealed ARDs will mainly serve to build tempo, slowing down the game to setup Mother. 

[EX2-053] ARD-08 Optimizer is a big play once Mother has 5 or more digivolution cards, which allows searching and playing another 10-cost of less D-Reaper from deck. If this card manages to search for another Optimizer, the process repeats itself. However, due to it's massive 10 play cost, we do not (yet) see him essential.

[EX2-054] ARD-09=Gatekeeper has a [Recovery] and a global [SecurityAttack-1] effect on top of him being played for free from security, which should be a very effective device to slow the game. 

Meanwhile, [EX2-047] ARD-03=Pendulum Feet has a simple [On Play] effect that searches and replenishes the player's hand, and should see itself played at 4 copies per deck.

Synergy With Other Cards

At the moment, there is no doubt that D-Reaper is a late game deck, and with all late-game decks it becomes imperative to slow the game usually by means of recovery.

Security control comes into mind, and yellow cards become natural in this deck. [BT6-089] TK and Kari would work well in this deck, having favourable conditions where your security would likely be lower than your opponent's since a D-Reaper deck would likely not attack until Mother is properly setup. 

Other recovery cards such as [BT6-100] Reinforce Memory Boost should also work well in this deck, and with recovery comes security effects such as [BT6-101] Wyvern's Breath and [BT4-105] Tactical Retreat which would work very well with ARD-09=Gatekeeper.

With enough yellow tamer, it is also possible to play the yellow Hybrid Digimon route with this deck. [BT7-038] Jetsilphymon remains an efficient recovery card as ever, while the LV4 hybrids should give this deck a final hit potential. 

Within EX-02 itself, another strong recovery Digimon can be found in [EX2-018] MarineAngemon. Against a D-Reaper deck, it is possible for the opponent to hard-cast Digimons for a swarm aggro win, since the D-Reaper engine (so far) may not be able to react to a large given memory (apart from ARD-01=Juri) in the early game. However, some deck optimisation may be needed to ensure MarineAngemon's recovery condition can be resolved (having opponent's Digimon without digivolution cards).

If this route is taken, then cards like [BT7-086] Himi Tomoki , [BT5-088] Sora and Joe, and [EX1-068] Ice Wall may come in handy. It might also be possible digivolve MarineAngemon into [BT8-112] Imperialdramon Paladin Mode for a board wipe!

BT8 Tier-2 Deck: Blackwargreymon

Blackwargreymon was a hot topic during the time this card is revealed. People felt excited not only because they like Blackwargreymon from the anime, but also Bandai has given a totally new mechanic for his deck.

Looking at the current BT8 meta where Imperialdramon and Mastemon are dominating the tournament, Blackwargreymon only can make it to Tier-2 in BT8 format.

Playing Blackwargreymon deck is like playing a Greymon Tribe deck. Things need to be setup for the big boss to appear, need to play more tamers to save the digivolution cost or gain more memory, option card is a must to delay or save the game in early phase.


Building a BlackWarGreymon Deck

There are some different builds of Blackwargreymon deck, but the new set of Blackwargreymon's evolution line in BT8 New Hero set is the core for the deck's mechanics.

The [BT8-058] Agumon is the best for searching power, we can put to hand a LV6 Blackwargreymon and a Digimon with [Greymon] in its name (so both LV4 Greymon and LV5 MetalGreymon are qualified for the search). The Agumon can be free-played when we hard-play Nokia tamer for 3-costs, or you will just hard-play him for 3 cost as that is maybe the reset-memory in opponent's turn. 

The [BT8-064] Greymon, a black Digimon that can be evolved from a black or red LV3 Digimon. This Digimon gives the LV6 Blackwargreymon "blocker" in opponent's turn because BT8 Blackwargreymon is both red and black Digimon. With the Blackwargreymon's "All Turns" effect, the Blackwargreymon can block twice (but normally opponent won't attack if there is a "blocker" Digimon that has higher DP than their Digimon).

[BT8-011] Cyclomon is a LV4 black and red Digimon and a Dragonkin type. Even though it is not a Digimon with [Greymon] in its name, but it is a Dragonkin type that can be searched from BT8 Agumon, and this Digimon can be evolved from both black and red Agumon which is more flexible for the deck. On top of that, this Digimon's inheritable effect is to destroy 1 of opponent's Digimon with 2000 DP or less. It is a convenient way to destroy those annoying LV3 Digimon, such as Bokomon.

The [BT8-067] MetalGreymon, it would be better if it takes only 3 cost to digivolve into this Digimon like other LV5 Digimon, but no, it costs 4. At least it triggers "De-digivolve 1" on 1 opponent's Digimon, then delete 1 opponent's Digimon with 3000DP or less (sound good to deal with the armor release (Armor Purge)).

The most important role of Metalgreymon lands in his inheritable effect where he can grant Blackwargreymon the ability to attack the unsuspended Digimon. With the DP's boost from LV3 Agumon (ST7 Agumon and promo Agumon), Blackwargreymon can have 14000DP (without considering about which Digitama it has under its digivolution source). And again, if Blackwargreymon destroys an opponent's Digimon, he can be unsuspended once.

Blackwargreymon takes 4 costs to digivolve into, and he can delete 1 opponent's tamer and 1 opponent's Digimon as long as the play-cost of those cards add up to 6 (4-cost to play Tamer and 2-cost to play Digimon). But normally we are able to delete only 1 Tamer or 1 Lv4 or lower Digimon.

The important of Tamers and DarkGaiaForce.

Both Marcus Daimon and Nokia are important for the deck, the more tamers we play in early game, the more memory we can gain back later. But this is also the weakness of this deck.

Dark Gaia Force is a very very important card of the deck. With 8-cost to play (equal to play cost of red Gaia Force), this card can destroy 2 opponent's LV5 or 1 LV6 or 1 LV7 Digimon or clear out all the rookies. Usually we should put more Dark Gaia Force in the deck hoping some of them stay in security stack.

The Weakness of the Deck

It takes too much time to set-up the digivolution source for Blackwargreymon while there are too many fast-pace decks in current meta. On top of that, we have to build the digivolution source inside the nursing area to keep it safe, beside, we need to play more tamers in early game in order to have enough memory to digivolve into Blackwargreymon while not passing our turn. 

Once the Blackwargreymon appears in the battle area, it focuses too much on destroying opponent's Digimon instead of their security stack, so for sometimes we didn't recognise that the opponent has already finished our security LOLx.

In this case, consider using the EX1 Metalgreymon to grant Blackwargreymon "piercing" is the right way to optimise for the deck. With "piercing" and "security attack+1" from ST1 Greymon, maybe Blackwargreymon will have better chance.
