Only 39 copies of the card were printed, and I'm going to guess that most of them wouldn't be graded a PSA 9 at this point, given that it's been 27-some-odd years since the card was first printed
While we don't have to mulligan until we find an engine piece, these are the cards that make the deck powerful, so a medium hand without a Sram or Spiritdancer is often worth mulliganing, especially with London mulligans making it hard to have a truly unplayable six-card hand, in the hopes of finding a Kor Spiritdancer or Sram, Senior Edificer
Awesome idea
Players are eagerly anticipating next weeks bans, hoping that red Aggro decks are taken down a peg or four
The only condition is the cards must also be from Genetic Apex, meaning, for example, that collecting the promotional Butterfree card from the special Lapras ex event won't count towards the 150 total despite it being among the first 150 Pokmon
