Not sure if there's a thread like this already, but i was just thinking about a few mons. For example Breloom with Technician, it's Mach Punch would be just as powerful as Scizor's Bullet Punch. It would get Force Palm or Low Sweep, each having their own uses boosted by technician. Maybe even a weird gimmicky Spore and Wakeup Slap set. It's Bullet Seed would also be pretty powerful. I'm also waiting for DW Gigalith because it'd be beastly in a sandstorm (in theory).
Anyways, what unreleased DW abilities does everyone else think would be really awesome?
