pokemon black white booster box B&W Base Set Pokémon Mega Excadrill ex Pokémon TCG: Scarlet & Violet

Luckily, I can think of a few great homes for this spell

You still need the requisite loyalty counters to activate abilities, but plus abilities and zero abilities are usable immediately (still just one per turn, though)

I what card shops use so I know that these were what I was predominately looking at, but thats enough of that

The trigger event doesn't have to specifically refer to legendary permanents or to artifacts, nor does it have to specifically refer to when something "leaves the battlefield." For example, an ability that triggers "whenever a creature dies" would trigger twice if a legendary creature or an artifact creature dies while Gandalf the White is on the battlefield, as would an ability that triggers "whenever a permanent is put into a graveyard from the battlefield." Look at each legendary permanent and each artifact as it exists on the battlefield, taking into account continuous effects, to determine whether any triggered abilities will trigger multiple times
