At the beginning of your combat phase, Ayara triggers, returning Scourge of the Throne from your graveyard to the battlefield, and giving it haste until end of turn.
When Scourge of the Throne enters the battlefield, Blasting Station triggers, untapping Blasting Station.
Declare Scourge of the Throne as an attacker, attacking an opponent whose life total is higher than or equal to yours.
Scourge of the Throne's dethrone ability and second abilities trigger.
Resolve the second Scourge of the Throne trigger, causing you to untap all attacking creatures and to get an additional combat phase after this one.
Holding priority, activate Blasting Station by tapping it and sacrificing Scourge of the Throne, dealing 1 damage to any target.
Resolve the second Scourge of the Throne trigger from step 3, doing nothing.
Repeat each combat phase.
This loop transforms your combat step into an endless cycle of devastation by continuously resurrecting and sacrificing your heavy hitter. It all begins when Ayara, Widow of the Realm pulls Scourge of the Throne straight from your graveyard with haste at the start of combat, triggering Blasting Station to stand at the ready. When Scourge of the Throne charges into battle against the player with the most life, its dethrone ability grants it a counter while its second triggered ability grants you an extra combat phase. Before that extra combat resolves, you sacrifice Scourge of the Throne to Blasting Station to blast an opponent for 1 damage—and because Ayara, Furnace Queen can bring it right back next turn, or rather, because the recursion engine resets every single combat, you can loop this entire process indefinitely across infinite combat phases.
