Cornerstone Mask Ogerpon ex
Cornerstone Mask Ogerpon ex arrived with Prismatic Evolutions on 17 January 2025. Here is what it does once it is on the table, and what it is worth right now.
What the card itself says
Every line in this block is copied straight off the card. Nothing rounded, nothing judged.
ITS ABILITY
ITS ATTACKS
Printed exactly as it appears on the card.
What to make of it
Every line below comes from a number. Either it is printed on the card, or we counted it on tournament lists. You will not find a score here — you will find what matters when you decide whether to run it.
WHAT IT HAS GOING FOR IT
- Retreat cost 1. One Energy to discard and it is back on the Bench, which matters a lot on the turn you need to swap attackers.
- It has an Ability, Cornerstone Stance. An Ability costs you no attack, so you can use it and still swing the same turn.
- Mega Zygarde ex / Barbaracle runs it in 15 of the 20 lists we have read, seen across 15 different tournaments.
- It is a Basic Pokémon. You can put it down on your very first turn, with nothing to evolve through.
WHAT TO WATCH OUT FOR
- It is an ex card. The turn it goes down your opponent takes two Prizes instead of one, and games do turn on exactly that.
- Weakness Grass ×2. Against a Grass Pokémon, apply that to the damage it takes — it climbs fast. Of the 1,351 tournament lists we have read, 848 run at least one Pokémon of that type.
- Mark H, and that is the letter the next rotation takes away. After that you will not be able to play it in Standard.
What it costs
We have no price to show you for this card today. The link below takes you where it sells, and you will see the day's numbers there.
Who plays it
We read tournament decklists one by one. The match is made on the set code printed at the bottom of the card, the one the player copied onto the list — never on the name, because two cards sometimes share one.

Paste it here and we'll replay each of your decisions hundreds of times, then tell you which one actually cost you the game.
