オムスター (pcg10_ja-17) is a Stage 2 Water-type Pokémon from the ワールドチャンピオンズパック set with collector number 017. It has Pull Down, which returns the highest Evolution from each of your opponent’s evolved Pokémon to their hand, and Hydrocannon, which does base 30 damage plus up to 40 extra damage depending on extra Water Energy attached. Its single Colorless retreat and Lightning weakness shape how you might include it in an energy- and matchup-aware deck.
