Blue - Gabumon Bond of Friendship
In BT6 Double Diamond, we already have the combo red BT6 Agumon and Agumon – Bond of Courage, it can deal up-to 3 security cards (LV3 Agumon contributes <Security+1>, and Agumon – Bond of Courage can trash 1 opponent's security card (2nd effect)) and destroy 1 opponent's digimon with 13000DP or lower. But the blue combo of BT6 LV3 Gabumon and LV7 Gabumon – Bond of Friendship is even better.
The combo of [BT6-019] Gabumon and [BT6-030] Gabumon Bond of Friendship can check 3 opponent's security cards and return up-to 3 opponent's level 5 or lower digimon to the bottom of their deck because the second "when attacking" effect of LV7 Gabumon Bond of Courage is not limited [Once Per Turn], so as long as the LV7 Gabumon can be unsuspended and do another attacking, it can remove one more opponent's lv5 or lower digimon to bottom of their deck.
The Tamer [BT6-088] Matt Ishida is a must for this deck, this is a very good 3-costs tamer card since he can give more memory and draw power for the deck. If the deck use Hammer Spark or Delay option card, the cost to evolve from LV3 to LV4 Gabumon is not the issue. If we are not building a blue ST8 Veemon to Ulforce or Gabumon LV3 to LV7 warp evolution Rookie Rush deck, white Tamer Nokia Shiramine can be considered to put in the deck since we can play 1 LV3 Gabumon for free when we play this tamer.
Security Control: Babamon joins Force
The yellow Babamon is currently the hottest candidate to be included in Security Control deck. Its "On Deletion" effect can be used to summon 2 Lucemon that can do <Recovery+1(deck)> for each Lucemon, or can summon a LV6 Rosemon for free. We don't know if BT6 is going to give another Rosemon, else the Rosemon from BT1 is maybe the best candidate for now.
Rosemon also can be a stepping stone to evolve into Chaosmon Valdure Arm in the same turn when Rosemon is summoned for free due to Babamon's "On Deletion" effect. This strategy is suitable for a Security Control deck.
Seven Demon Lord and Three Musketeer
We have "Legend-Arm" in BT3, "D-brigade" in BT4, and now we are going to see "Seven Demon Lord" and "Three Musketeer" archtypes. Will there be new deck profile focusing on these unique type?
Until today, BT6 have revealed 2 Musketeers LV6 digimon, red MagnaKidmon and black Gundramon, we are expecting a last musketeer to be the purple-colored BelleStarmon.
The BelleStarmon is last digimon in Three Musketeer. In BT6 we also have black option card Gewalt Schwarmer, 7 cost to play. As long as we have a [Three Musketeer] type digimon in the battle, we can play it ignoring color requirement. This is a very strong option card for a Megazoo deck (even if you need to pay 7 cost to use it) as it destroys all Digimons LV4 and below, and some LV5s. It's a good way to deal with rookie rushes or wide-boards. Too bad though it cannot be activated from the security.
Meanwhile, regarding the "Seven Demon Lord" Digimons: Lucemon Fallen Mode, Leviamon, Demon, Belphemon Rage mode, Barbamon, Beelzemon and Lilithmon, we already have 2/7 of them released in prior sets: Beelzemon in BT2 and Lilithmon in BT3. Beelzemon is a popular card back in the BT2 meta, and Lilithmon is a recent hit with Lilith-loop engine (with Omegamon Zwart) in BT5 meta. Now with BT6, both Lilithmon and Beelzemon will have better support from new LV3 Impmon to retrieve [Three Musketeer] of [Seven Demon Lord] from trash. Not only is this one of the the easiest and cheapest ways to return a LV6 Digimon from your trash to hand, but also sets up a warp digivolution candidate for BT2 Beelzemon. This impmon will improve the consistency of corresponding purple decks.
The newly revealed BeelStarmon can be very good use in Security Control deck. This card will be a scary weapon for purple color, as well as Megazoo.
Musketeer is going to become a hot topic or hot meta in BT6 Double Diamond.
The Part 3 will be coming soon …
