Other: Infinite ETB, Infinite LTB, Infinite storm count, Infinite magecraft triggers

Cast Quandrix Command by paying its mana cost, choosing its first and third modes. Holding priority, cast Naru Meha by paying its mana cost. When Naru Meha enters, it triggers, copying Quandrix Command, with the copy's first mode targeting Naru Meha and the copy's third mode targeting Crystalline Crawler. Resolve the copy of Quandrix Command, returning Naru Meha from the battlefield to your hand and putting four +1/+1 counters on Crystalline Crawler due to Corpsejack Menace. Holding priority, activate Crystalline Crawler three times by removing four +1/+1 counters from it, adding {2}{U}{U}. Repeat from step 2.
