What makes the Celebrations Pikachu particularly collectible is the context of its release
The Fairy Energy type included Fairy-type Pokmon (which were made up of Fairy-type Pokmon from the video games) like Clefairy and Togekiss, as well as Fairy-type moves
Its ability to learn the move 'Milk Drink' is a nod to its nurturing capabilities, providing a unique utility in battles and showcasing its endurance
The shard values honor and community, fielding knights and noble beasts that fight with integrity
Theres something kind of extraordinary about seeing the blank cards on a computer screen, with their attributes being typed in, right onto the card
It's also worth noting that trading will eventually be added to the game, so if you don't want Shop Tickets or Flair, maybe consider saving some rarer cards for trades down the road
