For Ice Beam v Air Slash, expound a bit more. Air Slash hits a lot of things harder, virizion, zoroark, serperior, liepard, escavalier, ferrothorn, whimsicott, and altogether provides better neutral coverage. Ice Beam still hits the genies, haxorus, hydra, and krook harder though, and since they are so much more common its the better option, but Air Slash isn't just for Scrafty.
