Think something like Jojo's Bizarre Adventure or another manga series where one of the combatants is trying to figure out just what the hell his/her opponent's power is.
Who among our cast do you think would be able to realize Ekko's trick in time to counter it?
IMO, these Champions could figure it out: 
Casi Y1 votesNasus is a dog, he never would. Zilean definitely should, he can travel back in time, too.
But what do you do against someone who can turn back time? Better don't pick the fight.
Svddenly1 votesI would've said read the lore for Nasus...
but Rito has reduced it to a paragraph that doesn't explain anything.
But yes, Nasus is a very smart dog and would be able to figure it out.
Casi Y1 votesSmart for a dog. But for a human? Look at his kit, he cannot be. Ekko throws a steak on the floor and the fight is won.
