This clever little engine turns the recurring nightmare of Traveling Plague into a relentless loop by abusing its mandatory return clause whenever its host dies. You sacrifice the enchanted creature to Woe Strider's ability, which conveniently lets you scry along the way and sends the Aura straight to the graveyard. Because Traveling Plague looks for its host to leave the battlefield rather than requiring it to be a legal target, it triggers itself to return to the battlefield attached to whatever fresh body is available. That's where Gremlin Tamer comes in, pulling double duty as a payoff engine by triggering its eerie ability every single time the Aura re-enters, flooding your board with an endless army of Gremlin tokens while you sculpt your library to perfection.
