Neo Discovery is a set in the Neo series. It was released on June 1, 2001. The printed size is 75, and the checklist is the same length. Tyranitar is 12/75, in position 12 of 75 on this checklist. Before it is 11 Smeargle, and after it is 13 Umbreon. The listed rarity is Rare Holo.
Tyranitar is a Stage 2 Darkness Pokémon with 100 HP. The card lists level 54. In the Pokédex this is Tyranitar (#248), generation 2 (Johto). The card says it evolves from Pupitar. In this catalog that name is Pupitar (#247).
Hironobu Yoshida illustrated this card. The same name is on 38 other cards in the catalog.
Tyranitar (#248) has 47 other cards in the catalog. Those other cards are in 30 sets. The other printings with a release date run from 2001 to 2026. The earliest other card is Tyranitar 31/75 in Neo Discovery (2001). Both list 100 HP. The rarity there is Rare, and here it is Rare Holo. 46 other cards of Tyranitar list a different HP.
The attack Slam lists 30× damage. The cost is Colorless, Colorless, Colorless. Flip 2 coins. This attack does 30 damage times the number of heads. Trample is another attack lists 50 damage. The cost is Darkness, Darkness, Colorless, Colorless. For each Benched Pokémon in play (yours and your opponent's), flip a coin. If heads, this attack does 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Resistance is Psychic -30. Retreat cost is 3. The flavor text reads "Its body can't be harmed by any sort of attack, so it is very eager to make challenges against enemies."
I keep a set binder for Neo Discovery, meant to hold every card of that set. This card is one slot in the Neo Discovery set binder. A generation binder holds one card of each species. Tyranitar can fill a slot in Generation 2 binder (Johto). I still need this card.
