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.

A strength
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.
A strength
It has an Ability, Diamond Coat. An Ability costs you no attack, so you can use it and still swing the same turn.
A strength
Mega Diancie ex / Dusknoir runs it in 56 of the 56 lists we have read, seen across 52 different tournaments.
A strength
It is a Basic Pokémon. You can put it down on your very first turn, with nothing to evolve through.
A strength
Mark I. It is one of the marks currently accepted in Standard: H, I, and J.
Keep in mind
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.
Keep in mind
Weakness Metal ×2. Against a Metal Pokémon, apply that to the damage it takes — it climbs fast. Of the 9,011 tournament lists we have read, 1,270 run at least one Pokémon of that type.
