How it works
Cast Mirage Mockery by paying its mana cost, targeting a creature you control.
Holding priority, cast Naru Meha either from your hand or from the command zone by paying 2 plus commander tax, if applicable.
When Naru Meha enters the battlefield, it triggers, copying Mirage Mockery, targeting Naru Meha.
Resolve the copy of Mirage Mockery, creating a token copy of Naru Meha.
Put either Naru Meha into your graveyard due to the legend rule.
Repeat from step 3.
This clever pairing spins up an endless loop of legendary replication by putting Naru Meha, Master Wizard's enter-the-battlefield trigger to work on the spell that birthed her. When you cast Mirage Mockery to copy a creature and follow it up with Naru Meha entering the battlefield, her ability targets that very spell on the stack, creating a brand-new token copy of the wizard herself. State-based actions immediately demand that you send one Naru Meha to the graveyard due to the legend rule, which handily sets the stage for the newly resolved copy to trigger all over again.
