This clever loop transforms a humble zero-mana artifact into an infinite engine by leveraging Emry, Lurker of the Loch and her ability to repeatedly pull Welding Jar straight out of your graveyard. Every time you recast that Welding Jar, Displacer Kitten's blink trigger swoops in to reset Emry, bypassing summoning sickness the moment she returns thanks to Rising of the Day granting haste. The result is an endless cascade of artifact sacrifices, enters-the-battlefield triggers, and self-mill that can fuel whatever fiery conclusion you dream up in Commander, Legacy, Oathbreaker, or Vintage.
