Yanma (#193) has 19 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 2001 to 2025. The earliest other card is Yanma 17/75 in Neo Discovery (2001). Both list 60 HP. The rarity there is Rare Holo, and here it is Uncommon.

The attack Grand Loop lists no damage number. The cost is Colorless. Draw 2 cards. You may switch Yanma with 1 of your Benched Pokémon. Spinning Tail is another attack lists no damage number. The cost is Grass, Colorless. Flip a coin. If heads, this attack does 20 damage to each of your opponent's Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fire ×2. Retreat cost is 1.
I keep a set binder for Unseen Forces, meant to hold every card of that set. This card is one slot in the Unseen Forces set binder. A generation binder holds one card of each species. Yanma can fill a slot in Generation 2 binder (Johto). I still need this card.
