>>15424835My Shuckle is Toxic, Wrap, Rest, Protect with Leftovers+Contrary. It worked pretty well in BW2 against the battle train (Doubles) but probably wouldn't against players, mostly because it wasn't EV trained or bred for IV/Nature.
I just Toxic, Wrap and Rest when I need to with a Protect between each move and get some more health. Occasionally I switch into Leech Seeded enemy as well.
