This ingenious loop locks down the game by turning your end step into an infinite recursion engine. You begin by casting Time Warp to secure an extra turn, while Repository Skaab enters the battlefield and uses its exploit ability to sacrifice itself, immediately pulling that very same Time Warp back from your graveyard to your hand. Meanwhile, Golbez, Crystal Collector keeps the value flowing with surveil triggers whenever artifacts enter, but its true power shines at the beginning of your end step: once you control four or more artifacts, its triggered ability reaches into your graveyard to return Repository Skaab directly to your hand, ready to restart the cycle on your next extra turn.
