So I've been toying with this in the lab a little and I've noticed that zelda has really good kill moves. They kill a lot earlier than sheik's moves (with horrible DI from the middle of dreamland, puff can be KO'd at: 73% from a sweetspotted bair, 85% from a sweetspotted fair, 96% from an fsmash, 107% from an uair, 110% from an upsmash if the last hit connects, etc.). So, before I do a lot more testing on this, is switching between sheik and Zelda allowed in tournament? I feel like it is but people just don't for how much worse of a character she is or how long the transformation takes. If you can get an opponent high enough or far enough off the stage, I think it's way easier and way more efficient than edge guarding.
tl;dr: sheik is really good but would be better with zelda's kill potential. is this legal? has this been tried?
