Omanyte is Pokédex #138, generation 1 (Kanto). Omanyte is a Stage 1 Water Pokémon with 70 HP. The card lists level 37. The card says it evolves from Helix Fossil. The card lists Omastar, Omastar (#139) under evolves to.
Omanyte sits at 69/100 in Majestic Dawn, position 69 of 100. Before it is 68 Munchlax, and after it is 70 Pikachu. The set belongs to the Diamond & Pearl series. It was released on 1 May 2008. The printed size is 100, and the checklist is the same length. The listed rarity is Common.
Call Up is listed as Poké-Power. Once during your turn (before your attack), you may flip a coin. If heads, search your discard pile for Helix Fossil, Dome Fossil, or Old Amber and put it onto your Bench. This power can't be used if Omanyte is affected by a Special Condition. The attack Wash Over lists 20 damage. The cost is Water, Colorless. Does 10 damage to 2 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Grass +20. Retreat cost is 1. The flavor text reads "A Pokémon that was resurrected from a fossil using modern science. It swam in ancient seas."
Omanyte (#138) has 14 other cards in the catalog. Those other cards are in 13 sets. The other printings with a release date run from 1999 to 2023. The earliest other card is Omanyte 52/62 in Fossil (1999). That card lists 40 HP, and this one lists 70 HP. Both list the rarity Common. Kagemaru Himeno illustrated that card, and Suwama Chiaki illustrated this one. 10 other cards of Omanyte list a different HP.
The illustrator line reads Suwama Chiaki. I count 102 other cards in the catalog with that illustrator.
Majestic Dawn set binder is where a full Majestic Dawn set goes. This card fills one slot there. A generation binder holds one card of each species. Omanyte can fill a slot in Generation 1 binder (Kanto). I still need this card.
