So for my collection purposes I keep a database of each Pokemon’s cards with unique artwork. Upon adding the Pikachu Outbreak! XY-P promos to my list, Pikachu currently stands at 101 cards in my database and that’s not even including any super nitpicky variations like the red-cheeked Base Set Pikachu or background artwork variations like how the Japanese Pikachu World 2010 card came with a green or a blue background.

The only Pokemon who even comes close to Pikachu is Unown and, well, that’s sort of a cheat anyway because the TCG thought we needed Unown A-Z three different times before just going with generic Unown [word] cards in the HGSS block. Congrats on hitting 100, Pikachu!
