The SpA drop is annoying, but if you think you may need to use the draco meteor then you have two options lead with it so you can switch it out to reset and come back in and fire off some other move or save it for late game to ruin someones' day once you weakened it down a little. of course if you choose against the scarf there is the white herb to negate the stat drop and allow you to fire off another one. The accuracy is unavoidable (see what I did there) I guess it's better than focus blast missing always, I missed 8 consecutive focus blasts that's all its' pp and a 0.006561% chance of happening.What I'm trying to say is what you give is what you get.

Happy to give VGC teams a rate, the gimmicky the better.
