>>22794026If you mean abusing Contrary in particular, no. If you're asking for what to fill in the rest of the set with:
Depends on the tier, and what in particular you want to fuck over. The cool thing about Serperior is that it's largely capable of choosing its counters.
Wanna beat Blissey/Chansey? Run Taunt+Synthesis.
Wanna cripple Crobats/M-Beedrills/tons of other fast shit on the switch? Run Glare.
Wanna break through Scizor/Skarmory/Ferrothorn? Run HP Fire.
Wanna OHKO Dragons that switch in on the Leaf Storm? Dragon Pulse.
Want to run Life Orb without the nasty recoil? Giga Drain will fix that.
Team having status problems? Run Aromatherapy.
For something that basically has 3 viable attacking moves there are a surprising amount of things you can do with it.
