IF SOMEONE SAYS THE WORD FOOTSTOOL, I'M THERE. Yo Ike doesn't have too great of a footstool game, but there are some uses. A setup I invented myself is Uthrow (no DI or DI forwards) into forwards hitting Bair (mostly standard), into footstool. This works because we do a running jump to hit the Bair, allowing us to follow their knockback into a footstool.
Our best footstool opportunities are probably from Nair on certain DI, as demonstrated
here.
Footstools I've theorized but never actually gotten yet are weak hit Dair to footstool, and tipper Fair (out of a running jump in order to follow knockback) into footstool.
Btw, sick movement. People really need to start using ledgejump into perfect waveland on platform on stages like YS and WW.
