Strategy & play
How Cornerstone Mask Ogerpon ex plays — derived from its stats and the rules of the game, not an opinion.
- A Basic — hits the board turn 1 with no evolution tax.
- Its main attack (Demolish) needs 3 Energy — a turn-3 swing on manual attachment — you’ll want Energy acceleration to power it up on time.
- Hits for 140 — one-shots small Basics and support Pokémon, but trades down into the format’s big attackers.
- Needs Fighting Energy to attack — your line must supply that color.
- Fighting type, weak to Grass ×2 — a Grass attacker doing ≥105 effectively one-shots it.
- A two-prize Pokémon — each KO gives the opponent 2 Prizes, so a single bad trade can lose the race. Back it with single-prize attackers.
How to beat Cornerstone Mask Ogerpon ex
- Exploit its Grass weakness — ≥105 damage one-shots it.
