Ninja boy is just a tech for OHKOs and a way to recycle your Koko, I have a Max Potion and itll be used depending on the situation. I have a new list that can be viable in the upcoming worlds.I don't get why you'd want ninja boy in Koko deck since you can't use the ability?
And are you talking about using Drampa's second attack which deals more damage if there is damage on your bench? In which case you wouldn't want to max potion...?
