07Why Collectors Want It

Original WotC-era printing from the Gym Challenge set — foundational vintage Weezing.
Weezing — the Poison Gas Pokemon and final evolution of Koffing, a Kanto-original Poison-type.
Required for any complete Weezing master set across eras.
Collectors of the Gym Challenge set need this card to finish it.

08Competitive Playability

Tier: None

Stage 1 Weezing with 70 HP; top attack around 20 damage. Functions as an evolution-chain piece rather than a tournament attacker.

09Card Moves and Abilities

Spontaneous Explosion Cost: Grass + Grass · 10+ damage

Flip a coin. If heads, this attack does 10 damage plus 30 more damage and Koga's Weezing does 30 damage to itself; if tails, this attack does 10 damage.

Toxic Cloud Cost: Grass + Grass + Colorless · 20 damage

Flip a coin. If heads, the Defending Pokémon is now Poisoned. It now takes 20 Poison damage instead of 10 after each player's turn (even if it was already Poisoned).

Weakness: Psychic ×2
Retreat cost: 2

10Grading and Population

PSA 10 estimate: WotC-era Weezing PSA 10 populations vary; small numbers across most sets.

Graded copies command notable premiums over raw, especially for 1st Edition prints.

Other graders: BGS and CGC also grade vintage Pokemon; PSA dominates secondary-market liquidity.
