Well the goal of this deck is quite simple and very very aggressive. But it does have its downsides. The first one is the fragility of the combo. You need your opponent to have a Digimon with no sources in play. You also need very specific pieces to execute the OTK lines. But I did build the deck in a way that allows it to generate a lot of attacks even without the full combo which makes that burden a little lighter. As for the combo itself it involves the EX 3 Crabmon, Ebidramon, any Level 5 in the deck, and Regalecusmon. It also requires enough memory to go into Regalecusmon without passing turn. Preferably you can attack with the Level 4 with Jamming then go into MegaSeadramon to unsuspend the stack for another attack. But that requires an additional 3 memory and you to have the stack on field already. Now here is the combo. Attack with Regalecusmon, on attack play out Crabmon and Ebidramon from its sources. Crabmon gives Regalecusmon jamming and you can slot a source from hand underneath Regalecusmon. This can extend combos drastically. Ebidramon gives Regalecusmon blocker and unsuspends Regalecusmon. That is one check. Attack with Regalecusmon again. Using the inherit from one of the Level 5s, slot Ebidramon or Crabmon underneath Regalecusmon to unsuspend Regalecusmon. It depends on what else you have in hand to tuck underneath Regalecusmon. You can then attack with Regalecusmon again which then lets you play out the Crabmon or Ebidramon again. Both on plays trigger once more. By slotting more cards underneath your Regalecusmon you can even put more of the Level 5s underneath it to continue the assault on your opponent. I have achieved 15 attacks in a row with only the commons and uncommons in this deck. Yes the entire combo line is pauper format legal. I have posted that list before. This is the standard format build of the deck. I put a lot of time and effort into figuring out how to make it as aggressive and consistent as possible. But it still has problems. It doesn't like Ace cards, doesn't always have jamming, needs your opponent to have no sources on a stack, and has protection from battle only. This makes the deck very fragile but very potent when it goes off. It is the definition of a glass cannon deck. But it sure is fun to play.
