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
330 HP. Only 4 cards in Pitch Black carry more.
A strength
Slowking runs it in 8 of the 62 lists we have read, seen across 8 different tournaments.
A strength
Mark J. It is one of the marks currently accepted in Standard: H, I, and J.
Keep in mind
Retreat cost 3. Once it is out front, it stays there. Pack something that moves it another way, or you will burn whole turns discarding Energy.
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 Darkness ×2. Against a Darkness Pokémon, apply that to the damage it takes — it climbs fast. Of the 5,392 tournament lists we have read, 3,349 run at least one Pokémon of that type.
