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 Woe Strider by sacrificing Naru Meha.
When Naru Meha dies, Graceful Reprieve triggers, returning Naru Meha from your graveyard to the battlefield.
Repeat from step 3.
Resolve all Woe Strider abilities from step 5.
By looping Naru Meha, Master Wizard with the copy of Graceful Reprieve she generates upon entry, you create an endless cycle where she repeatedly enters and leaves the battlefield. Woe Strider acts as your essential sacrifice outlet to cleanly send Naru Meha to the graveyard, triggering the delayed return effect of Graceful Reprieve while simultaneously letting you convert all those deaths into infinite scry triggers.
