pokemon groudon card Team Magma's (011/025) your turn ends The Most Valuable Groudon Cards

If a face-down permanent you control leaves the battlefield, or if the game ends or you leave the game while you control it, you must reveal it to all players (even though in this case, everyone saw it before it entered)

Mutating this with Edgewall Innkeeper suddenly makes your card draw engine a lot more resilient

Its best to save it for when youre ready to cast a game-finishing combo that may require a good chunk of mana

However, he also has the ability to "Turn target permanent you control to its other face"...though he isn't able to use that ability on himself

Unique Abilities Cards that have unique abilities or mechanics can also be rare and valuable

TCGplayers grading guideline says that damaged cards may not even be sleeve playable, but its certainly better than the mutilated corpse of a Magic card than I was half expecting to receive
