Cornerstone Mask Ogerpon ex
Cornerstone Mask Ogerpon ex has appeared in several sets: Twilight Masquerade (TWM 112) and Prismatic Evolutions (PRE 58). It is the same card every time — it plays the same, only the artwork and the price change. Here is what it does once it is on the table.

What to make of it
Have a look at what it does well, then at what will get in your way. After that you'll know whether it belongs in your deck.
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.
- Azumarill runs it in 23 of the 31 lists we have read, seen across 21 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 2 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 3,150 tournament lists we have read, 1,922 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.
