Smash Ace
It's not because I personally suck at the matchup. It's because the matchup is really, harder than most people think. ZSS has her armor pieces which she can keep on the stage for a pretty long time. She has her speed against Ike, projectiles that stun, and a great spacing tool. I think it's really safe for me to say that ZSS is Ike's worst matchup, even worse than Falco and Olimar. Hell, even Renegade admitted that ZSS is a tough matchup.
