Made this deck after I saw the new duramon, and realised that marsmon might be able to come back as a stand alone deck now thanks to the new duramon, giving the deck new OTK potential. the idea is essentially to have enough memory is shove a duramon under the grap leomon, and then digivolve into marsmon to blitz and then to raid into a unsuspended digimon. then with the raid, you will trash two cards from their security, gain some memory with either, your bt15 biyomon and birdramon inheritables or your bt14 Tais, and then to gain memory with marsmon effect when he switches attack targets. then you can attack for two checks with marsmon. if you are lucky enough to have 4 memory to shove two duramons under grap, that is essentially an OTK with trashing 3, checking 3 when he unsuspends, and then Omni blitz for game.
this deck isnt that great in my opinion, there are probably a lot of other cards that can be utalized. like if you want a memory setter, you can remove two yoleis and add two sec +1 tai kamiyas, in order to further confirm the OTK potential, the yolei was mainly there for you to gain more memory at the start of your turns.
but this was my inspiration for a marsmon otk deck. Hope yall enjoy or make your own renditions.
