This Gruul combo deck wins by looping Basking Broodscale with Blade of the Bloodchief for infinite mana and Spawn tokens, so shutting off their activated abilities is premium. Cursed Totem stops Basking Broodscale's Adapt and the Spawn tokens' sacrifice-for-mana ability. Karn's static ability stops Blade of the Bloodchief's Equip, Springleaf Drum, and Haywire Mite from being activated. Vexing Bauble counters any spell cast without mana and otherwise cycles for a card, so it is a cheap artifact that digs us toward our answers. Ulamog, the Ceaseless Hunger comes out since at ten mana it's too slow against a deck that can combo off before we ever cast it. Our two existing Dismembers stay in, since they can kill Basking Broodscale (a 2/2 before counters) or Glaring Fleshraker (2/2) before the loop starts. Keep Karn, the Great Creator in to find Trinisphere from the board, which taxes their cheap combo pieces like Blade of the Bloodchief and Springleaf Drum.
