Expensive to cast, but thats why we play Commander, right
Over the years, Metal-type Pokmon have carved out a definitive identity in the game, and they have one of the most streamlined play styles
The physical Pokemon TCG has tried to make this balance work, with Hidden Fates serving as one of the best sets to pull this off, while some Sword & Shield sets in the past capitalized on Shiny Pokemon in all the wrong ways
However, every Hideaway card has another ability on it in the case of the lands, they have ability that, if you meet certain requirements, let you play the exiled card without paying its cost, while the creature lets you put it into your hand when the creature leaves the battlefield
So, be sure to take care of it and keep it intact
