pokemon mewtwo mega card M EX (64) (64) 064 - Holofoil XY BREAKthrough When 1 of your Pokémon becomes a Mega Evolution Pokémon Pokemon - Mega-Mewtwo-EX 160162 -
Description
The Soul Stone This is the really BIG money card of the set, and WotC knows it
Its attack trigger pumps out Meteorite tokens that deal damage when they enter and tap for mana without going to the graveyard
Then, the turn proceeds as usual, where the second strike's attack damage is resolved at the same time as the defender's damage (as in normal combat)
One underappreciated option is to name the card that would cause a problem right now rather than trying to stop a long-term threat
