Well, anyone got a Pokemon Platinum they'd willingly donate me? Mine vanished randomly.
Hi thar Fox.
Successful? I would say... no. Maybe if you ditch Vacuum Wave on the typical Specs set for something else, but the only noteworthy option I can think of off the top of my head is CC, only for the sake of killing off Blissey. Take a stab at it yourself [/failpun], if you want.
Lucario @ Specs, Modest/Timid, 4 HP/252 SpA/252 Spe
Hidden Power Ice/Hidden Power Rock
The only other sets that wouldn't have priority moves aren't too successful, such as a Reversal Set, or if you've got some crazy idea, a Mixed set.
And guess what? Togekiss and Mew can learn Softboiled!
