Ingot Chewer - Affinity hate

Wispmare - Stony silence aka our worst enemy

Riccochet Trap - Counter straight up own us if not dealt with

Timely Reinforcements - RDW sidehate (this deck out races us pretty consistently)

Blood Moon - just a general good move seeing so many decks rely on so many non basic lands in modern
