A universe where hot chips don't exist :(
Thanks. Goodra has a chance to get Recover as an egg move from Milotic, once PokeBank opens up.A while back, PS thought Goodra had access to recover, but was later disproved and it was taken off. As for Outrage, I think it unlocks, but it will end the rampage and confuse the user.
And I think you're right about Outrage. It doesn't work correctly in PS ATM.
For Trevenant? The standard set is:Can you recommend a set please?
252 HP / 4 Atk / 252 SpDef
Careful Nature (+SpDef, -SpA)
It's a great tank, and can run either physical bulk or special. Will-O-Wisp helps with that. The Sitrus set here is great for forcing switches with its Substitutes. If the opponent stays in they often risk significant residual damage and a burn.
If you want something a little different, try the Lum Berry set. It uses the same EVs and nature, ect. but the moves you can choose are much more flexible. Use Rest, as it gives Trevenant full, instant healing and allows it to absorb status for your team. Then you can go for WoW, Leech Seed, Horn Leech, Shadow Claw, Toxic, Curse, ect.
I wouldn't recommend running SubSeed without a Sitrus Berry though. That set works because Sitrus provides passive healing, and you don't have to stop SubSeeding to use Rest.
