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
350 HP, and nothing in Chaos Rising goes higher. That is the wall your opponent has to break through before taking a Prize.
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, Mortal Shuriken. An Ability costs you no attack, so you can use it and still swing the same turn.
A strength
Mega Greninja ex runs it in 65 of the 65 lists we have read, seen across 60 different tournaments.
A strength
Mark J. 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
It is a Stage 2. You have to come through Frogadier to get here, or find a Rare Candy to skip the middle step.
Keep in mind
Weakness Lightning ×2. Against a Lightning Pokémon, apply that to the damage it takes — it climbs fast. Of the 5,392 tournament lists we have read, 439 run at least one Pokémon of that type.
