I find our best landing options are sometimes between Rush Coil mixups, bverses, and then most ideal; the item metal blade. Say a person is in a midst of a combo or string, your only options would normally be to air dodge or use fast aerial, but if you have an item, you invinciblade. (Which is air dodge then zair.)
It's one of your best "get off me options" since a z-drop is 1 frame. Nair, and bair are also pretty good. Fair sometimes if you're predicting a player is waiting for you to land because of its hitbox range. I've never used dair to land despite knowing the exact auto cancel range. I just don't like messing up, but maybe I should try it more.
