Interesting; I was thinking people would go for Skill Swap with Spinda for something like this, but, this actually seems a lot more effective; Serperior certainly isn't as dead weight as Spinda would be after Skill Swapping... if only Victini had some form of recovery ):
But imo it seems like you have that initial combo and then just the same few Pokemon you always use, though, so aside from Serperior and Victini it doesn't seem like anything new... Probably my only problem with this
