is there a better wallbreaker in ou than landorus?

And I’m not talking about sand force choice band landorus. I'm not talking about landorus-therian either. I'm not even talking about rock slide landorus-incarnate which is a mix of the two. I’m talking about earth power focus blast sludge wave calm mind landorus incarnate with the sheer force ability and 331 speed and timid nature, ohkoing clefable with a single boost and outspeeding base 100s while 2hkoing almost everything in the tier with its vast movepool and coverage, releasing STAB earth powers and not getting walled by anything except cress and mega latias, which are not even common in ou, on top of the opponent not knowing what moves you are running until its too late
