  • Bulk-leaning spread (139 Defense / 172 Stamina) — it stays on the field longer, which suits shielded PvP formats.
  • A second charged move costs 75,000 Dust and 75 Candy, and with 3 charged moves to pick from it is the single biggest PvP upgrade you can buy.
  • Its moves get a damage boost in Rainy weather — worth timing raids around.
