pokemon first edition shadowless booster box Base Set Pack 1st 1999 Pokemon 1st First Edition

That comes from my particular experience, but the card is probably better in more capable players' hands

June 6th: Black Bolt and White Flare featuring all 156 Unova Pokemon

Pokmon cards value is determined by three core factors: rarity (how limited the print run is), condition (physical state from Mint to Damaged), and demand (collector and competitive player interest)

Gardevoir's "Psybeam" (90 damage + confusion) can disrupt your entire strategy

It can be OK as a cheap mini wrath for a control player who can get some use out of the other ability with tokens etc but at that it is not worth a cube slot, certainly not a gold one
