As for toon links zair, it is very understandable to want to change it from always guaranteeing a usmash. Either two things happen when i use the move.
1- opponent gets hit with zair, slightly pushing them back.
This is cool, and i can work with this. After the zair lands, i can time a dash attack. If it hits, like OBM said, toon link can land dsmashes. Giving him a small combo.
2- opponent gets hit by zair, and gets sent to the ground to tech.
I still see this happen, at mid to high %'s. So there is still opportunity for an usmash or force get up from a dash attack or arrow.
the thing i want to know is, what exactly differentiates the two states. Is it percentages ?
