Well this deck is pretty aggressive. The goal is to turbo through your deck to get to the BT 8 Kimeramon with a MadLeomon Inherit and using the Kimeramon effect to place the Crowmon underneath it. Attack. End of attack delete from the effect of MadLeomon. Inherits play back the Deltamon and MadLeomon from trash. Deltamon trashes a card from your hand to add back the Kimeramon to your hand. DNA and attack to repeat. This is an infinite by the way. The rest of the deck is just stuff you can use to keep yourself alive while helping you achieve the combo. Honestly as long as you keep the rookies and the consistency pieces the rest of the deck is just whatever you want to run for defense.
