Mega Diancie ex
Mega Diancie ex has appeared in several sets: Phantasmal Flames (PFL 41) and Ascended Heroes (ASC 267). 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, Diamond Coat. An Ability costs you no attack, so you can use it and still swing the same turn.
- Mega Diancie ex / Dusknoir runs it in 37 of the 37 lists we have read, seen across 34 different tournaments.
- It is a Basic Pokémon. You can put it down on your very first turn, with nothing to evolve through.
- Mark I. The next rotation takes mark H away, so this one stays tournament legal.
WHAT TO WATCH OUT FOR
- It is a Mega Evolution ex, and that is the most expensive rule in the game. The turn it goes down your opponent takes 3 Prizes instead of one. They need six to win, so 2 knockouts on this card are enough. Send it out knowing that.
- Weakness Metal ×2. Against a Metal Pokémon, apply that to the damage it takes — it climbs fast. Of the 3,150 tournament lists we have read, 464 run at least one Pokémon of that type.
