gx pokemon cards TCG Colorless Retreat Cost Machamp-GX | Burning Shadows |

You do get some benefits as well, which makes it quite powerful

(2004-10-04) If either target is illegal at the time the ability resolves (whether because it has left the battlefield, because it has gained Shroud or Protection, or for any other reason), the ability taps the remaining target, but no damage is dealt

The reason why this card is so valuable is not only because it is of an iconic character like Ugin the Spirit Dragon, but rather a combination of its mechanical power as a value engine and also its physical rarity as a full-art, halo foil of this already hard-to-find chase card

Its a great choice for Kanto fans and an excellent value, especially after its reprint price
