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. Staryu is 32/160, in position 32 of 164 on this checklist. Before it is 31 Seadra, and after it is 33 Mudkip. The listed rarity is Common.
Staryu is a Basic Water Pokémon with 60 HP. In the Pokédex this is Staryu (#120), generation 1 (Kanto). The card lists Starmie, Starmie (#121) under evolves to.
Tomokazu Komiya illustrated this card. The same name is on 248 other cards in the catalog.
Staryu (#120) has 29 other cards in the catalog. Those other cards are in 27 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Staryu 65/102 in Base (1999). That card lists 40 HP, and this one lists 60 HP. Both list the rarity Common. Keiji Kinebuchi illustrated that card, and Tomokazu Komiya illustrated this one. 19 other cards of Staryu list a different HP.
The attack Lunge lists 20 damage. The cost is Colorless. Flip a coin. If tails, this attack does nothing. Weakness is Grass ×2. Retreat cost is 1. The flavor text reads "It appears in large numbers by seashores. At night, its central core flashes with a red light."
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. Staryu can fill a slot in Generation 1 binder (Kanto). I still need this card.
