well, actually, this is a deck i make on whim, so dont expect much. just fun.
change ancient leaf if you play solo
its hard to fusion buster since no kaiju are dragon type. to deal with this, you can have neos fusion first to discard rainbow dragon, or use prologue to discard destruction sword fusion and buster blade, and pray so the opponent use dragon type and you have buster blader in hand, so next turn, you can take back yur fusion by discarding a hand, and then fusion using enemy monster.
