Eldrazi Tron leans on a huge number of artifacts (Expedition Map, Talisman of Curiosity, Trinisphere) and colorless lands; Fade from History wipes their artifact board including any Constructs or Talismans while giving them only a 2/2 Bear in return, a great rate. Collector Ouphe shuts down Expedition Map and Talisman of Curiosity entirely, severely slowing their mana development. Keep your mana dorks and combo pieces intact since this matchup is a race to resolve your engine before they land Karn, the Great Creator or a big Ugin.
