This loop turns a clever adventure-style mechanic into an engine for infinite mana and triggers, all fueled by the cost-reduction of Arcane Melee. By casting the Seething Song half of Blazing Firesinger, you net a surplus of red mana thanks to the discount, which is then used to pay for Emiel the Blessed's blinking ability. When Blazing Firesinger re-enters the battlefield, it resets its prepared status so you can cast Seething Song all over again.
