This is an interactive Mono-Black Control precon built around Gollum, Riddle Master. Designed to mirror the atmospheric psychological warfare of Gollum’s cavernous home beneath the Misty Mountains, this deck forgoes traditional linear creature strategies in favor of forcing opponents into tough choices, resource attrition, and constant mind games. Gollum lands early on turn two, forcing opponents to play around your odd/even guesses every time they cast a spell. To maximize Gollum’s triggers, the deck runs a suite of cheap protection and recursion spells, like Undying Malice, Feign Death, Not Dead After All. When Gollum is targeted or sacrificed, you bring him back to reset his choices and keep drawing cards, draining life, and pumping his stats. Instead of letting opponents build wide armies, you police the board with forced-sacrifice edicts (Plaguecrafter, Fleshbag Marauder, Witch-king, Bringer of Ruin) and tactical sweepers (Toxic Deluge). As opponents attempt to draw their way out of your riddles, Orcish Bowmasters and Mirkwood Bats passively ping their life totals and build your board, while Painful Quandary and Call of the Ring apply relentless turn-over-turn pressure. Once the board is locked down, slip Gollum or the Witch-king past enemy defenses unblocked using The Black Gate or Key to the Side-Door to finish off remaining opponents.
