Many of you might now be wondering why Im telling you this
On its own, its a big beatstick that can potentially win the game if it attacks uninterrupted
Ryan Hay (he/him) has been writing about Magic: The Gathering and video games for years, and loves absolutely terrible games
You can move an Energy to pay for a Retreat Cost, then move any other Energy on the field to your new Active Pokemon to get it to attack on the same turn
You've then also got the fact that it's both a creature and an equipment, which means there are more ways to fetch it up in those formats too
