Like most Pokmon cards, the value of Charizard-GX depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Burning Shadows)
Well, take 2 damage from my Megrim or tax them with Smothering Tithe - which is a card I would love to add to this deck as a suggestion, but it's way out of budget
One way to tell if you have this particular version of the Charizard is to look for the 1 st edition emblem in the middle of the card towards the left
A scene alive with detail
Honorable Mention Chaos Orb Chaos Orb represents colorless removal for any permanent in the game, effectively working as a swords to plowshares and disenchant combined
And considering the card's importance to competitive play during the Pokmon TCG 's Sword and Shield sets era, Mew VMAX will likely continue being this valuable in the future
