This clever loop relies on Emry, Lurker of the Loch to continuously replay Welding Jar from your graveyard for zero mana, utilizing Emry's tap ability while Displacer Kitten provides the blink engine. Every time you cast the zero-mana Welding Jar, Displacer Kitten's avoidance trigger targets Coercive Recruiter, exiling and returning it to the battlefield. That new entry triggers Coercive Recruiter's ability to untap Emry, refreshing the merfolk so you can tap her again. Meanwhile, you can sacrifice Welding Jar at will to protect your artifacts, all while generating an endless sequence of artifact and creature triggers to overwhelm your opponents.
