Tron's gameplan revolves entirely around artifacts and lands like Expedition Map, Urza's Tower/Mine/Power Plant, Bonder's Ornament, and big artifact threats like Maelstrom Colossus and Pinnacle Kill-Ship, making Dust to Dust extremely valuable for exiling two key pieces like Expedition Map or Bonder's Ornament, or even hitting a Boulderbranch Golem. We cut Phyrexian Walker and Ornithopter since this matchup is about racing before Tron assembles, not grinding small blockers. Keep our curve low and aggressive, since Tron's removal suite is otherwise light until they get their engine online.
