green wing base set booster box Sold at Auction: Pokemon Unl. Green-Wing Sealed 1999 Pokemon TCG Green Wing

When the effect of an Spell, Trap or Effect Monster is activated, you can return 1 face-up "Mist Valley" monster you control to its owner's hand and negate the effect of the card and destroy it

This really is just an absurdly powerful payoff and the best face card out of all of the four decks

Ensure the sacrifice effect every turn by sacrificing the Shaman to himself each time and you should be golden

The downside is that they are so faithful that they often are chock full of mostly useless cards

The typical used copy of Dark Charizard is worth quite a bit less though, with most selling for somewhere in the region of $220
