Trick Scarf P2 is like a slower normal-type Cresselia that's a lot harder to predict at preview. It retains most of the matchups of regular P2, but can now Trick on Sylveon and Fini, as well as some faster taunters like Heatran and Corviknight. Its speed is sufficient to kill Adamant Band/LO Shifu, so while it's definitely no hard counter it can cheese a few wins. The speed lets it outspeed zygarde-complete, while the bulk is enough to almost always tank and kill Regieleki (except a hit from Thunder which has a small chance to kill). HP definitely did something but it's slipped my mind what exactly. This P2 also has a hilarious Necrozma matchup where you get +1 spa, steal its specs, and then OHKO it with Hyper Beam.
