This crafty loop begins by leveraging a successful Rogue attack to cast Notorious Throng for its prowl cost, securing an extra turn while flooding the board with Faerie Rogues. When you follow up by casting Pinnacle Monk, its entry ability immediately plucks Notorious Throng back out of your graveyard to hand, setting you up to repeat the process on your extra turns. Meanwhile, Dour Port-Mage acts as the engine's quiet core: its activated ability bounces Pinnacle Monk back to your hand for reuse, which simultaneously triggers the Mage's passive card-drawing ability to keep your hand fully stocked.
