This is a very aggressive deck that's whole thing is using the Dracmon lines effects to digivolve into Undead and Dark Animal cards from your trash. You do pay the cost but you can use these effects to rip an opponent apart and access cards such as DexDorugoramon to help clear fields or GranDracmon to go wide. By trashing SkullBuluchimon you can Evo into any of your cards in trash. The Promo SkullGreymon lets you clear fields and play out your rookies from trash once more. Combine this with the on play of the promo Dracmon and you can go into another Level 4. GranDracmon gives you free evos from trash as well. If at any point you can go into the card while you have a second Level 5 on field you can get a free DexDorugoramon. You can also evolve your level 3s into DexDorugamon which gives you removal for low powered Digimon. Blackgatomon gives you blocker and retaliation. Is this deck good? It isn't meant for competitive. But it is a fun deck to play.
