Gruul Basking Broodscale wants to flood the board with Eldrazi Spawn tokens and creatures like Glaring Fleshraker and Devourer of Destiny in a single big turn off Urza's Saga and ramp lands; Force of Despair wipes out all creatures that entered this turn, punishing their explosive starts. Consign to Memory counters colorless spells outright, which lines up well against their many colorless Eldrazi threats like Devourer of Destiny and Emrakul, the Promised End, and it also stops triggered abilities like Glaring Fleshraker's spawn creation. Cut the slower Faithful Mending and reanimation-focused Persist since this matchup rewards proactive disruption over incremental card selection against a deck that can bury you in bodies quickly.
