Learned some cool moves a little while ago.
I have been testing out approaching with out of shield bair. Just testing out the usefulness of this. It adds a whopping 1 frame extra to turn around before shielding.
Also, I think Ike is a lot better in the water than I thought. It's really simple but I don't really see other Ikes abuse this.
If we jump+aerial as close as possible, we short hop an aerial with very little water lag. We don't go very high either, so we can basically spam all of our aerials. Bair and Uair become especially useful, and Dair isn't that risky to use on someone anymore.
An easy way to test this is to go into the water, and Hold up/down and mash A+Jump (preferrably X/Y) for uair/dair, since order doesn't really matter much in the water as long as you're mashing A fast enough.
