1995 magnemite pokemon card · Base Set First Edition #53(Shadowless) This is of the Common rarity. 1999 Pokemon Base Set Magnemite

Ixalan is a world dominated by four creature types - Merfolk, Vampires, Dinosaurs and Pirates, so maybe this is a nod to that

It would be printed in other future stand alone expansion sets, but it would not be seen in Seventh, Eight or any of the other core non-expansion sets

Pikachu is always the first card you think of when someone mentions a fast Pokemon

Your options are Riku of Two Reflections, Talrand, Sky Summoner, Melek, Izzet Paragon, or Toshiro Umezawa if you want to get really out there with it

The deck had no right to be playing Feed the Swarm in Mardu, and I can only imagine it was there in the precon to reduce the power level of the deck relative to the others, and synergize with Olivias lifegain

With the Psychic type including several Legendaries and Mythicals, we can expect EX cards of Lugia, Latios & Latias, Necrozma, Jirachi, etc and Gardevoir is bound to benefit them
