Builds for 7 star Delphox

I recommend Heatran, Arceus, Armorouge, and Blissey.

You cant go wrong with Heatran because hes got the perfect defensive and offensive typing for this matchup. But he needs support, ideally from an Acid Sprayer. That can be either Arceus or Armorouge. Both work fine and can hit hard without dying. Blissey you can do without, but it never hurts to have one setting up walls and healing teammates.

Ceruledge I see a lot of people recommend but in my experience he takes too much damage from psychic and doesnt synergize with Heatran like Armorouge and Arceus do.
