aerodactyl pokemon card 1995 - (1) - Fossil Preserved in a tamper 1999 Pokemon Fossil 1 Aerodactyl-holo

T he Bandai copyright line shows a later year (e.g., 2001) in the bottom-right

The only downside is that this doesnt really enable any of blues archetypes, but it looks like a solid playable regardless

it could be Lingering Souls, Obzedat, Tragic Slip, whatever

So knowing this about the first two Pokemon in this line and looking at this specific Porygon-Z, the main reason you would want to use this card in a deck is for its Digital Reboot move, the reason you would want to use this move so often is to be able to reuse an Ability from let's say a Stage 2 Pokemon every single turn, like Aggron from Dragons Exalted (if you're playing in the expanded format) where you can use its Toppling Wind Ability to discard the top 3 cards of your opponent's deck every single turn and hopefully be able to win the game that way
