>>30658281Primarina is high UU, it was the only one of the starters to get an OU discussion thread. Incineroar is probably gonna be RU, or even NU depending on the metas there and how it holds up in them.
It's by far gonna be the best of the three in Doubles once its HA comes out. Even in Singles it's gonna work out as an alternative to Arcanine and probably jump a tier, but no higher than UU.
