This attack does 20 damage to 2 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

Primal Clash is a set in the XY series. It was released on February 4, 2015. The printed size is 160. This checklist is longer, at 164 cards. Magcargo is 23/160, in position 23 of 164 on this checklist. Before it is 22 Slugma, and after it is 24 Magcargo. The listed rarity is Uncommon.
Magcargo is a Stage 1 Fire Pokémon with 120 HP. In the Pokédex this is Magcargo (#219), generation 2 (Johto). The card says it evolves from Slugma. In this catalog that name is Slugma (#218).
Shigenori Negishi illustrated this card. The same name is on 151 other cards in the catalog.
Magcargo (#219) has 29 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 2001 to 2026. The earliest other card is Magcargo 33/64 in Neo Revelation (2001). That card lists 80 HP, and this one lists 120 HP. Both list the rarity Uncommon. Shin-ichi Yoshida illustrated that card, and Shigenori Negishi illustrated this one. Retreat cost there is 3, and here it is 4. 27 other cards of Magcargo list a different HP.
The attack Flame Burst lists 20 damage. The cost is Fire. This attack does 20 damage to 2 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Flamethrower is another attack lists 90 damage. The cost is Fire, Colorless, Colorless. Discard an Energy attached to this Pokémon. Weakness is Water ×2. Retreat cost is 4. The flavor text reads "Its body is as hot as lava and is always billowing. Flames will occasionally burst from its shell."
I keep a set binder for Primal Clash, meant to hold every card of that set. This card is one slot in the Primal Clash set binder. A generation binder holds one card of each species. Magcargo can fill a slot in Generation 2 binder (Johto). I still need this card.
