Play EX9 soundbirdmon to dig through my deck, although I can just hard play scatter modes since the negamon egg reduces play cost of digimon with "negamon in text" by 2. Rarely have to evolve into EX9 assembly eyesmon for rush damage; mainly evolving straight into ST17 rapidmon or EX9 rareraremon for de-digivolving. If have BT1 mimi on board while controlling ST17 rapidmon and/or megagargomon ace, can move abbadomon core from breeding to battle area and cause massive damage/change the game dynamic to a sure win. Alternatively could assemble abbadomon using negamon eggs to cheat out abbadomon core that way. Blitzgreymon as alternative lvl6 backup ace counter.
