Yeah, I remembered you mentioning a Drain Punch & DD Scraggy in my egg moves thread.
I'm a bit of a Pawniard fan, if they've got Defiant, so the Sucker Punch/SR idea sounds great to me.
As for the others, the Dark Pulse Zorua is something I actually knew about, but didn't remember in time, & I don't really care about Piplup & Croagunk much...
But anyway, I'm not sure if there is a way to get both Dark Pulse & Earth Power on Deino. I don't think there is, but if you've got an idea, I'm all ears.
