Flip 2 coins. For each heads, discard 2 cards from the top of your opponent's deck.

Weezing is Pokédex #110, generation 1 (Kanto). Weezing is a Stage 1 Psychic Pokémon with 110 HP. The card says it evolves from Koffing. In this catalog that name is Koffing (#109).
Weezing sits at 28/124 in Fates Collide, position 28 of 129. Before it is 27 Koffing, and after it is 29 Mew. The set belongs to the XY series. It was released on May 2, 2016. The printed size is 124. This checklist is longer, at 129 cards. The listed rarity is Uncommon.
The attack Balloon Bomb lists no damage number. The cost is Colorless, Colorless. Flip 2 coins. For each heads, discard 2 cards from the top of your opponent's deck. Thick Liquid is another attack lists 80 damage. The cost is Psychic, Colorless, Colorless. Both Active Pokémon are now Confused and Poisoned. Weakness is Psychic ×2. Retreat cost is 3. The flavor text reads "Very rarely, a sudden mutation can result in two small Koffing twins becoming conjoined as a Weezing."
Weezing (#110) has 28 other cards in the catalog. Those other cards are in 24 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Weezing 45/62 in Fossil (1999). That card lists 60 HP, and this one lists 110 HP. Both list the rarity Uncommon. Mitsuhiro Arita illustrated that card, and Shin Nagasawa illustrated this one. Retreat cost there is 1, and here it is 3. 27 other cards of Weezing list a different HP.
The illustrator line reads Shin Nagasawa. I count 303 other cards in the catalog with that illustrator.
Fates Collide set binder is where a full Fates Collide set goes. This card fills one slot there. A generation binder holds one card of each species. Weezing can fill a slot in Generation 1 binder (Kanto). I still need this card.
