Boros Control aims to lock you out with land destruction (Cleansing Wildfire, Field of Ruin, Demolition Field) and efficient removal (Path to Exile, Solitude, Galvanic Discharge) while Wrath of the Skies and Price of Freedom suppress your board presence. Consign to Memory is essential for stopping their haymakers and protecting your combo pieces on the stack. Teferi, Time Raveler shuts off their instant-speed interaction and lets your sorceries resolve safely, which is critical against Reprieve and Solitude. Mystical Dispute provides cheap counter backup since they're a blue-adjacent control deck with white permission elements. Thoughtseize and Prismatic Ending come out because hand disruption is slower against a land-destruction deck that wants to deploy threats at sorcery speed, and Prismatic Ending is redundant removal in a matchup where countering their key permanents is more important than destroying them.
