This clever loop relies on the fascinating interaction between persist and replacement effects to turn a humble spirit into an endless supply of ammunition. When you sacrifice Restless Apparition to Blasting Station, its persist ability normally brings it back with a -1/-1 counter, but Vizier of Remedies steps in to reduce that counter placement to zero, keeping the Apparition completely clean and ready to persist again. Every time Restless Apparition enters the battlefield, Blasting Station untaps itself so you can immediately sacrifice it anew, translating the endless cycle into infinite damage and death triggers for your opponents.
