The Trainer card known as Area Zero Underdepths is a Stadium that allows both players to have up to eight Pokmon on their Bench if at least one Tera Pokmon on either side is in play

The most thought of example of this is the 1999 base set Charizard which can sell for well over $100,000 if in good condition

The ones with perfect fit slide in like in the Deckbox

Ive personally been playing two copies in my sideboard of Blue-Red Murktide and have been loving it, as your opponent generally brings in more removal spells to combat your creatures in post-board games, and a planeswalker like Jace is the perfect foil to that plan

Again, traditional Pokmon collectors may not have much of an interest in owning a Katy Perry card over, say, a base set Charizard
