Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Return to Action, with the copy targeting Naru Meha.
Resolve the copy of Return to Action.
Holding priority, activate Woe Strider by sacrificing Naru Meha.
When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
Repeat from step 3.
Resolve all Woe Strider abilities from step 5.
This clever loop creates an unstoppable cycle by using Naru Meha, Master Wizard to endlessly copy Return to Action, which ensures Naru Meha returns to the battlefield every time it hits the graveyard. While the spell copy and resurrection handle the core recursion, Woe Strider provides the crucial sacrifice outlet to trigger Naru Meha's death and instantly manipulate your library with its built-in scry ability.
