Basic Eosmon engine with use of strong purple cards as spicy security secrets, Magnadramon for recovery and possible refill of security options.
Possible replacement of Armaggedemon for DanDevimon.
Omnimon Zwart Defeat is also obviously a good choice but it's not budget friendly at all and this is supposed to be a for fun deck.
Egg can be replaced with any other purple card as it will not be used, only there for option function.
