My take on a diaboromon deck after playing several locals. I found many lists online, and I used that to start, but I was finding my diaboromon were finding a lot of resistance in the security stack, so I added in the High-speed plugins to help with battles, as well as the BT2 diaboromon were added back in for the token generation with attacks and protection again from security digimon. I will play this a few times and see if the promo Kurisarimon with decoy would also be a good one to add.
V2.0: Win Rate added to tech in a warp infermon, and help with BT2 Diaboromon. I exchanged the Izzy's with the ST15 Tai, as blocking will trigger his effect. Then I swapped 2 Mamemon for 2 Metalgreymon's from ST15 for more blocking, and also inheritable Security Attack +1. Egg ratio's were swapped, as DP has become more important than card draw in this deck.
V2.5: BT2 Diaboromon never really got played, that 4 digi cost was just sometimes, more than I could afford and if I had the blocker and/or Security Attack Diaboromon also in hand, those were always better options, so I removed the 2 I had, which also meant that Win-Rate 60% just wasn't worth keeping around, as well as the 2 warp digivolving BT5 Infermon (even though I did use it to get some really quick turn 2 diaboromon's). Taking advice from other Diaborobros, I am focusing on 2 Diaboromons, the EX1 Blocker, and the Promo Security Attack, which are now 3 copies of each. I then added the Giromon for more blockers, and the inheritable will make my blocking tokens a danger for my opponent. Rounding out the replacements, 2 copies of promo Kurisarimon with inheritable decoy are back in! I had them in my original deck, but the meta at the time was less 'delete' and more 'de-digivolve/return to hand' but now I am seeing more security options popping my stacks, so hopefully with decoy, and the Blue plugin, I will be safer when going for a big promo diaboromon extra security check attacks, also my level 4's were kinda light.
V3.0: ACE is here! I have decided to go a more 'safe' route, with only EX1 Diaboromon for blocking, and ACE for some fun sniping. With the removal of the promo security attack +1 diaboromon, I don't see the need for High Speed Plug-in, but the Digivolution Plug-in was suggested to me, and it sounds like a great fit.
