What has it got in its pocketses? What Has It Got in Its Pocketses? is a mono-black Gollum deck built around one simple idea: every riddle should lead to another riddle. Gollum, Riddle Master, enters the battlefield and asks the table to play along by choosing odd or even. As opponents cast matching spells, Gollum works through his three rewards. Once the riddle has been fully answered, the deck is designed to sacrifice, bounce, or reanimate him so he can return and start the game all over again. Rather than being a generic mono-black goodstuff deck, the list leans heavily into Gollum's story and personality. Cards like My Precious, Call of the Ring, One Ring to Rule Them All, The Torment of Gollum, Claim the Precious, Nazgûl, and several different versions of Gollum keep the deck grounded in Middle earth. Mechanically, the deck plays like an aristocrats/reanimator precon. Sacrifice outlets such as Viscera Seer turn a finished Gollum into value, while cards like Unearth, Reanimate, Malakir Rebirth, Fake Your Own Death, and Kaya's Ghostform bring him right back for another riddle. Conjurer's Closet and Erratic Portal can reset Gollum without even needing him to die. The goal is not to solve the riddle once. The goal is to make the table answer it again… and again… and again. A strange little creature, an unhealthy obsession with a certain precious object, and a Commander who simply refuses to stay dead.
