(Typing this on phone so sorry if messy)
After watching sweep vs probs I playtested this set and it works great:
Palkia @ Leftovers
248 HP / 8 SpA / 252 SpD
Calm nature
- Toxic
- Rest
- Surf
- Thunder Wave / Fire Blast
Moves:
- toxic + rest is a must, allows this set to win 1v1 against most support arceus bc you can heal status and they can't. (4 spa judgment is a 4HKO doing max 30%). Allows Palkia to get past usual checks like lugia and is nice for hitting switchins / crippling setup sweepers like certain cm arc
- Surf is reliable stab, hits most things neutrally (only thing immune to it is like Gastrodon which dies to this set lel), also smacks stuff like Heatran and Lando t
- Thunder Wave nice to hit Xern switch ins, situationally more useful than toxic (eg having that scarf ogre paraed > poisoned) btw scarf ogre is doing a maximum of 29% with thunder :o
- Fire Blast over twave if Ferro and Scizor are problematic
- idk if dragon tail should be slashed, this would make Palkia function in the role of a bulky pseudo-lugia mon who isn't completely offensively helpless
Usage tips:
- stall arceus formes you can stall
- this is THE answer to most Kyogre so switch it in aggressively against that
- predict when using status (ie cripple switch ins, sometimes it doesn't want to stay in to status things as it will have to take a hit and rest is not too reliable recovery). So something like: switch in on ogre --> status the predicted switch in.
Team options
- cleric support provided by Xern/sylveon highly recommended
- something to deal with Ho-oh (ground type sr setters)
- all Mewtwo are bitches (taunt users generally suck), something to deal with that.
- physically based sweepers are generally bad news.
- opposing Palkia are generally bad too
- anything with Draco meteor is bad. This set fares poorly against giratina too
- again, fairy types help remedy a lot of this
- fairy types are both friend and foe - answer to them specifically Geoxern mandatory
- arceus ghost is sweet as it burns stuff and checks Mewtwo and checks palkia
- Defog support
