>>14645587Hammer Arm by Move Relearner. Devastation. Lots of Kalos mons get their best moves through Heart Scale tutoring instead of level up. I'm rocking Leech Seed, Spiky Shield, Seed Bomb, and Hammer Arm to great effect.
And does he not get Drain Punch at all? I'd heard he gets it from breeding, which is better than nothing, at even if not I'd be surprised if it didn't return as a tutor move next game.
