rare machoke pokemon card - 067/165 - Pokemon 151 - Reverse Foil Evolves from Machop Type Machoke - 087/196 - Lost

For example, if you activate Crypt Rats and pay X=5, then copy that ability, both resolutions of the ability will deal 5 damage

Switch in a Pokmon with about 60 health and you were almost guaranteed to defeat it in one turn.

When the Pokemon this card is attached to does damage to your opponent's Active Pokemon and that damage is affected by Weakness, the Weakness becomes 3 instead

Some of them even have upsides beyond simply stopping graveyard strategies
