So I'm trying to make a "trap" Omastar - it is the only Pokemon that can learn all three "trap moves". It's already got Spikes and Toxic Spikes, all I need now is to give it stealth rock. But seeing as though I have it in Black, it's not a TM and I would not like to waste my time gathering shards for the move tutor. PLEASE HELP! Any answer is much appreciated!
