No sideboard cards are available to bring in for this matchup, so the 75 stays the same. Against Mono-Green Eldrazi, Thoughtseize and Orcish Bowmasters help slow down their ramp into Emrakul, the Promised End or Ulamog, the Ceaseless Hunger, and Surgical Extraction can strip a copy of Green Sun's Zenith targets or cards put into the graveyard by Malevolent Rumble from their graveyard. Fatal Push should target Fanatic of Rhonas early to slow their mana acceleration, though Galvanic Discharge needs extra energy to kill its 4 toughness. Race aggressively with Ragavan, Nimble Pilferer and Voice of Victory since this deck is a ramp strategy that struggles against a fast, disruptive start.
No sideboard cards are available to bring in for this matchup, so the 75 stays the same. Against Gruul Basking Broodscale Combo, prioritize using Fatal Push, Galvanic Discharge, and Thraben Charm proactively on Basking Broodscale and Glaring Fleshraker before they generate Eldrazi Spawn tokens or grow out of removal range. Thoughtseize is key to disrupting their sequencing with Ancient Stirrings and Malevolent Rumble. Race with Ragavan, Nimble Pilferer and Ocelot Pride while using Surgical Extraction to strip a copy of Emrakul, the Promised End or Devourer of Destiny if you see one in the graveyard.
No sideboard cards are available to bring in for this matchup, so the 75 stays the same. Against Izzet Prowess, Wrath of the Skies is a premium sweeper for their small Dragon's Rage Channeler, Monastery Swiftspear, and Slickshot Show-Off board, and Thraben Charm can also pick off an individual key threat like an equipped Cori-Steel Cutter carrier. Galvanic Discharge and Fatal Push answer their one-toughness threats before they get out of hand with Cori-Steel Cutter equipped. Play around Lightning Bolt and Mutagenic Growth combat tricks when attacking with Ragavan, Nimble Pilferer, and use Ocelot Pride's lifelink to offset their burn-based race plan.
