Porygon-Z is Pokédex #474, generation 4 (Sinnoh). Porygon-Z is a Stage 2 Colorless Pokémon with 110 HP. The card lists level 54. The card says it evolves from Porygon2. In this catalog that name is Porygon2 (#233).
Porygon-Z sits at 6/106 in Great Encounters, position 6 of 106. Before it is 5 Pachirisu, and after it is 7 Rotom. The set belongs to the Diamond & Pearl series. It was released on February 1, 2008. The printed size is 106, and the checklist is the same length. The listed rarity is Rare Holo.
Conversion is listed as Poké-Power. Once during your turn (before your attack), you may discard a basic Energy card from your hand. Porygon-Z is the same type as that Energy Card until the end of your turn. This power can't be used if Porygon-Z is affected by a Special Condition. The attack Tri Attack lists 40× damage. The cost is Colorless, Colorless. Flip 3 coins. This attack does 40 damage times the number of heads. Weakness is Fighting +30. Retreat cost is 2. The flavor text reads "Additional software was installed to make it a better Pokémon. It began acting oddly, however."
Porygon-Z (#474) has 17 other cards in the catalog. Those other cards are in 14 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Porygon-Z DP35/56 in DP Black Star Promos (2007). That card lists 120 HP, and this one lists 110 HP. The rarity there is Promo, and here it is Rare Holo. Kagemaru Himeno illustrated that card, and Kent Kanetsuna illustrated this one. 16 other cards of Porygon-Z list a different HP.
The illustrator line reads Kent Kanetsuna. I count 74 other cards in the catalog with that illustrator.
Great Encounters set binder is where a full Great Encounters set goes. This card fills one slot there. A generation binder holds one card of each species. Porygon-Z can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
