2. When Patron of the Arts dies, it triggers, creating a Treasure token.
3. Resolve the Chthonian Nightmare ability, returning another creature card from your graveyard to the battlefield.

This ingenious loop transforms Chthonian Nightmare into a self-sustaining engine by utilizing Patron of the Arts to constantly refund your mana. Every time you sacrifice and recast the enchantment, Patron of the Arts bridges the gap by generating a Treasure token upon its death and re-entry to pay for the Nightmare's re-casting cost, while Cemetery Prowler quietly stands guard in the background to potentially discount your spells by sharing card types with exiled graveyards. Together, this dynamic loop endlessly recycles your graveyard to flood the battlefield with triggers and storm count.
