I got 15 no problem with Ike, with a bit of AI abuse.
Hang off the edge of the stage, jump up and hold away from the edge. With any luck, none of them will land a hit before you get away.
Get yourself quite far out, being lower than the stage, then use your midair jump to get underneath the ledge and use Aether to get back to hanging on the ledge.
A lot of the time the dumb AI will follow you too far off the ledge, and due to the non-flinching frames at the start of the move, these enemies won't be able to deal knockback, and you'll get safely back to the ledge while their lack of recovery causes them to fall to their death!
Aether can also spike them on the way down, so occasionally you'll be able to kill a few of them directly if they're hanging around off the ledge when you recover.
Good luck!
This idea is genius, did you make that up, or get it from a website.
