pokemon fire red leaf green booster pack Pokémon - FireRed & LeafGreen - Sealed Blister Loaded with tons of awesome Pokemon classic characters like Charizard Pokémon Vintage Fire Red Leaf

The duty counter means the creature shouldnt be able to harm you, barring blinking it or some other way of removing counters

Even if you dont think about Harnessing it, this is more than enough to make this card playable

The lid doesnt clip or slide on and off, as is common, but is held in place with strong magnets, making opening and closing super convenient

This combination of demand and rarity makes Mana Crypt the 4th-most-valuable card outside the Reserved List, behind two cards from Portal: Three Kingdoms (Imperial Seal and Zodiac Dragon) and one (Grim Tutor) which was exclusive to a particular 1999 starter deck
