Vexing Bauble is your most important piece of interaction here, completely shutting down Crashing Footfalls as well as their free evoke elementals like Force of Negation and Subtlety. Consign to Memory provides a clean, one-mana answer to the cascade trigger itself while it is on the stack. We trim some of the slower graveyard enablers and Emperor of Bones to maximize our density of cheap, stack-based disruption. Remember that Fatal Push easily destroys 4/4 Rhino tokens for just one mana without needing revolt, making it your best cleanup tool for anything that slips through.
