500 years booster box in the Future - This exclusive English edition brings together legendary characters and epic battles OP-07 | Future 500 Years

Unlike Mewtwo ex in TCG Pocket , which can wipe out most Pokmon cards with its powerful 150 damage Psydrive attack, Gengar ex tops off at 100 damage with its Spooky Shot attack

This ancient Pokmon card is one of those officially banned from tournaments

When your opponent activates a card or effect on the field (Quick Effect): You can send 1 face-up "Ashened" card you control to the GY

If you have a stack of raw cards you want to move, this is a very efficient platform for it

I don't get why I would want to do that to get me to a win

You may not wait and cast it later in the turn (unless of course the ability triggers and resolves again).
