Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Graceful Reprieve, with the copy targeting Naru Meha.
Resolve the copy of Graceful Reprieve.
Holding priority, activate Ashnod's Altar by sacrificing Naru Meha.
When Naru Meha dies, Graceful Reprieve triggers, returning Naru Meha from your graveyard to the battlefield.
