This matchup is a tempo-oriented counter-war where resolving your cascade spell with backup is the primary goal. Mystical Dispute is essential for fighting over their cascade enablers, Force of Negations, and Rhinos. Endurance is an easy cut since they don't utilize the graveyard and its 3/4 body cannot block 4/4 Rhino tokens effectively. Aggressively fetch your basic lands to insulate your mana from their post-board Blood Moons, and hold Subtlety to answer their Shardless Agents or their own Endurances.
