The base 100 in everything "pixies" have never been very great at sweeping, and I feel Victini is only slightly better. It has a huge attacking movepool, sure, but it lacks recovery, is weak to SR, doesn't learn trick, and (shockingly) does not learn calm mind. The accurate wisp is awesome, but it seems like Victini was made for double/ triple battles, and that's where it will really shine and surpass Jirachi and Celebi.
The sets are inventive, though, so hats off to you guys. But really, I feel Victini won't be threat in single battles until it has access to that special move.
