Relic Runner

A 2/1 for two whose evasion is a switch, not a stat: cast any artifact, legendary, or Saga this turn and the Rogue becomes unblockable for that combat. Evasion gated on a deckbuilding requirement is an old trick, but where prowess-style triggers pump power off any noncreature cast, this reward is binary. Either the historic spell went on the stack that turn or it did not, and note the verb: the card checks whether you cast the spell, not whether it resolved, so a countered legendary still opens the lane. The fragile body sets the terms. Two power matters far more when it connects every turn than when it eats a chump block, so the ability is doing the heavy lifting and the Runner is priced to die to anything if it ever gets stopped. The real strain is sequencing. Because the ability only cares about the current turn, the timing of a fetched artifact or a flashed-in legendary turns into a combat decision rather than a value one: run out the artifact before you attack and the Rogue walks in; hold it for a later turn and a blocker takes the two damage instead. That single-turn window is a cleaner balancing lever than a fixed activation cost, since it taxes the pilot's ordering rather than their mana. Load a deck with cheap legendaries and artifacts you already want to cast, and the historic condition becomes repeatable chip damage that ordinary blockers cannot answer.
