Block + Endeavor Xerneas

Xerneas @ Protective Pads
Ability: Fairy Aura
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Endeavor
- Moonblast
- Substitute
- Block
This Xerneas specializes in easily removing Necrozma-DM to let teammates like Zacian-C or another Xerneas abuse it. The idea is to take advantage of the fact that Necrozma-DM is basically forced to switch in when Xerneas is on the field. While it switches in, you can click subsitute. It will think you’re a standard geomancy set, and stay in. Next, you trap it with block. Then just sub to low hp and click endeavor. The last moveslot is used for Moonblast to give Xerneas a reliable source of damage output. The item is protective pads to prevent Necrozma-DM from healing while you die to rocky helmet damage. It also lets Xerneas defeat Ferrothorn. The EVs are put into special attack and speed to let Xerneas force out Pokemon and create opportunities to remove Dusk Mane. Timid lets Xerneas speedtie special life orb Yveltal, though Modest is probably fine.
