Sultai Control has Deadly Cover-Up as a full board wipe plus a deep suite of removal (Maelstrom Pulse, Shoot the Sheriff, Witherbloom Charm), so one-shot haste threats like Ball Lightning underperform compared to resilient late-game cards. Ark of Hunger provides incremental reach and lifegain to survive their long game, while The Dawning Archaic becomes cheap quickly and gives a huge reach body that also lets you recast burn from the graveyard, playing around their sweeper by being cast after board wipes have already happened. Choreographed Sparks and Flashback are cut since they rely on board presence or spells in the yard that a control-heavy plan will disrupt. Sequence burn spells to play around Deadly Cover-Up by not overcommitting into a single sweeper turn.
