Arceus ◇ is 96/131, in position 97 of 150 on this checklist. Before it is 95 Ultra Necrozma-GX, and after it is 97 Bunnelby. The listed rarity is Rare Prism Star.
Arceus ◇ is a Basic Prism Star Colorless Pokémon with 160 HP. In the Pokédex this is Arceus (#493), generation 4 (Sinnoh).
Masakazu Fukuda illustrated this card. The same name is on 471 other cards in the catalog.
Arceus (#493) has 34 other cards in the catalog. Those other cards are in 9 sets. The other printings with a release date run from 2007 to 2026. The earliest other card is Arceus DP50/56 in DP Black Star Promos (2007). That card is named Arceus, while this one is Arceus ◇. That card lists 90 HP, and this one lists 160 HP. The rarity there is Promo, and here it is Rare Prism Star. Kunihiko Yuyama illustrated that card, and Masakazu Fukuda illustrated this one. Retreat cost there is 2, and here it is 1. 34 other cards of Arceus list a different HP.
First Law is listed as Ability. Prevent all effects of your opponent's attacks, except damage, done to this Pokémon. The attack Trinity Star lists 30 damage. The cost is Colorless. You can use this attack only if you have Grass, Water, and Lightning Pokémon on your Bench. Search your deck for up to 3 basic Energy cards and attach them to your Pokémon in any way you like. Then, shuffle your deck. Weakness is Fighting ×2. Retreat cost is 1. The card text says: ◇ (Prism Star) Rule: You can't have more than 1 ◇ card with the same name in your deck. If a ◇ card would go to the discard pile, put it in the Lost Zone instead. The flavor text reads "It is told in mythology that this Pokémon was born before the universe even existed."
I keep a set binder for Forbidden Light, meant to hold every card of that set. This card is one slot in the Forbidden Light set binder. A generation binder holds one card of each species. Arceus can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
