Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Slip On the Ring, with the copy targeting Naru Meha.
Resolve the copy of Slip On the Ring, blinking Naru Meha.
Repeat from step 3.
This clever loop centers around Naru Meha, Master Wizard entering the battlefield and using her triggered ability to copy spells on the stack. By targeting Slip On the Ring—which you cast just before her—you create a copy that immediately exiles and returns Naru Meha to the battlefield. Because her blink triggers her ability all over again, this creates an infinite loop of creature entry and departure triggers, perfectly fueling any magecraft effects you might have in play.
