Making use of the Arukenimon/Mummymon engine to really make use of NSo's powerful top end, which right now is the strongest part. Use your purple cards to put Myotismon into the bin, then use the effect of the Arukenimon and Mummymon tamer to get it back. After that, you can digivolve Piedmon ACE on top of the Arukeni/Mummy, and use Myotismon's DNA effect to go into Boltboutamon before passing turn.
