This deck is about the new BT20 support. The playstyle is gonna be centered around building your resources with the multiple searchers we have in the table, to then digivolve into the BaoHuckmon (BT20-013) with a Gankoomon (BT20-057) in hand, play it, digivolve the Bao into SaviorHuckmon (BT20-014) to delete and then, at the end of the turn, digivolve into a Jesmon again and attack with either the < Blitz > of Jesmon (ST12-10) or Jesmon (BT20-017)'s effect. You can also digivolve the Gankoo into Gankoomon (X Antibody) (BT20-059) if we want an almost all-proof turn (unless your opponent invested in options/tamer effects) and < De-digivolve 2 > opponent. After that the table would be really hard to mess up with, and you will be able to DNA digivolve in your turn to Jesmon GX (BT20-021) or blast digivolve in the opponent's turn if they attemp to strike back. Either way this is a very explosive deck that has lots of utility/defensive support and can combo really fast. Beware of flood-gates, try to prioritize killing them with either SaviorHuckmon (BT20-014) or Jesmon (BT20-017).
We are getting two Jesmon (ST12-10) to have a bit more of Sistermon in the field, and also if you evolved this Jesmon on top of SaviorHuckmon (BT20-014), you can strike end of the turn with < S.Attack+1 > and < Alliance > with a minimum of 15000DP easily reaching around the 20000DP, checking three securities and leaving your opponent already trembling for next turn.
UPDATE: Main reason I prefer in this deck Jesmon GX (BT20-021) over Jesmon GX (BT10-112) is because of the DNA digivolution, the [When digivolving] effect might not be as broken, but the capability of DNA digivolving for 0 cost, attack with < Alliance > and then unsuspend, trash ideally at least two securities (which is more safe than checking) and then attack again with < Alliance > if you got enough digimon to suspend with is simply priceless. That plus considering you have been invulnerable last turn, you just cleaned potential ACEs that might fuck you up when attacking, and the factor that you might have alreaddy checked three securities with Jesmon... yeah, is a very strong deck.
Also, we will be having some digivolving from trash potential in this deck, this will depend greatly from the game, but Gankoomon (X Antibody) (BT20-059) and the Sistermon Ciel (Awakened) (BT20-084) are very safe trashes while searching for our pieces. Evade at all costs trashing Gankoomon (BT20-057) and BaoHuckmon (BT20-013) cause they really are your main combo start pieces, only if you are pretty sure that you have enough copies to go through. I might change a bit after testing and try to put inside some Red Scramble (LM-027) to be able to recover some things from the trash.
