Crosis

Crosis is a Grixis (blue-black-red) Commander control/discard deck built around Crosis, the Purger. Its game plan is to slow opponents down with spot removal, bounce, and counterspells, while repeatedly attacking hands with cards like Duress, Mind Rot, Wrench Mind, Syphon Mind, Ravenous Rats, and Chittering Rats.

The deck’s key synergy is combining hand disruption with tempo plays—bouncing or killing threats while keeping opponents low on resources until a finisher can take over. Looters like Cephalid Looter and Looter il-Kor help smooth draws, while mana rocks and fixing support the three-color control plan. It aims to win by grinding the table out of cards and options, then closing with Crosis triggers or big threats like Nicol Bolas, Planeswalker.
