NSo is very combo heavy and has to be planned out very carefully otherwise you lose the game. Try and play Nightmare Soilders as fast as you can cause Scapegoat will come in handy during mid to late game. Build up to Myotis in the back. Hard play lvl 3/4 digimon so you can start getting your trash loaded. Then hard play Piedmon, DNA into Boltboutamon and then try and keep the big body on board.
