Well, with that dimensional cape infinite crap this mathc up goes from very hard to impossible, but since most competitive environments are banning it, Ike can win.
Ike can kill Meta at very early percantages. That is pretty much the only advantage he has.
Eruption and Counter work wonders vs Meta. Being deceptive with your rolling helps a lot as well, and jab jab jab jab jab of course.
Full block tornado, and try to sidestep at the last "rotation" to get a a decent punish.
This match up is just instincts and playing smart. If you secondary somebody like Falco or Luigi I would suggest using them.
