If Yorick bans Irelia, there's really not a solid counter. Tryndamere is kind of one, but Yorick doesn't lose lane that badly and almost nobody even plays Trynd. Anyone saying Sion counters Yorick is talking straight nonsense. Jax is easy if you know the matchup. Nasus is immobile so once Yorick's W gets good late game, Nasus can't even look at Yorick and just gets slapped to death by ghouls. The reason I say almost is because the king of no-counter champs, Jayce, is too hard for people in bronze/silver/gold to play. But Yorick is relatively easy, so in low elo he's basically matchup-proof.

Gwen, Mordekaiser, Sylas (easy if bad), maybe Cho'Gath.
