I dismiss Jumpluff because its defenses are shit, but whatever, you can have your fun.
I'd be fine with merging the ideas of Quick Stall and Sun Stall together. I don't think it limits our options too much, and it also opens up some appealing ideas for stallish 'mons on a Sun team, most notably Sableye (which spinblocks extremely well when water-type attacks have their power halved) and Venusaur (excellent SubSeed 'mon that benefits a ton from Sun).
What do we call this, though? Quick Sun Stall? Whatever it is, I want my name on it.
