Try to use Contrary Spinda with V-generate (assist) and yoou'll find out how much a pain is to kill (use him as your last poke with rest and nothing bar crits kill her) is so funny because nobody everyone laughts at spinda, really fun to use
I prefer Charcoal Assist Liepard- With Prankster, Assist ignores all Speed Drops from V-Generate except vs priority moves, and with Charcoal + a boost from Drought, V-Generate gets 324 base Power.
Sucker Punch can be used on say Latias to stay faster than the competition that resists V-Gen (Shandera, Starmie, Latios), especially luring attacks behind a Substitute, while you could opt for Hone Claws to take advantage of the boosts obtainable after an Encore causes a switch. This way you can switch in on a non-threatening move, Encore, Hone Claws on the switch, and then Substitute against Taunt, status, etc. before hitting with a sun-boosted Assist V-Generate, always going first.
