Buy sideboard on ManapoolThis Gruul Eldrazi combo deck relies on Urza's Saga, Ancient Stirrings, and Malevolent Rumble to assemble Basking Broodscale plus Blade of the Bloodchief style value engines, so Force of Vigor is excellent for blowing up Urza's Saga or any artifact engine pieces for free. Endurance's evoke resets their graveyard against Emrakul, the Promised End's cost reduction (which counts card types in graveyard) and denies Malevolent Rumble/Ancient Stirrings recursion value. The extra copy of Wistfulness (cast for GG) can exile a problematic artifact like Urza's Saga or Ugin's Labyrinth while replacing itself, and its evoke mode also lets us discard down for value in a pinch. We cut narrow removal spells that don't answer their large Eldrazi threats (Devourer of Destiny, Emrakul) or their engine lands, favoring disruption that hits their actual game plan.
Izzet Prowess is a low-curve aggressive deck full of 1-2 toughness creatures (Dragon's Rage Channeler, Monastery Swiftspear, Slickshot Show-Off), making Brotherhood's End's 3 damage sweeper mode a great one-sided reset that also hits any Cori-Steel Cutter Monk tokens. We trim Quantum Riddler since its 5-mana body is too slow against their fast clock and its Warp mode leaves us tapped out against a deck full of cheap burn and counters like Consign to Memory. Keep Force of Negation and Subtlety at full count since they're premium against a deck that wants to jam threats and burn us out, and Subtlety can bounce a key Dragon's Rage Channeler or Slickshot Show-Off. Our Crashing Footfalls rhinos and Violent Outburst cascades provide the resilient bodies needed to race and block their small creatures.
Esper GenericBlink is a grindy midrange deck full of blue spells (Ephemerate, Orcish Bowmasters triggers care about draws, Teferi, Kaito) so Mystical Dispute is frequently a two-mana hard counter against their Solitude evokes or removal-adjacent interaction, and it also answers their own Mystical Dispute if boarded in. Endurance's evoke lets us proactively deny value from their graveyard (Overlord of the Balemurk mills, Emperor of Bones recursion) while also giving us a free flash blocker against Phelia or Flickerwisp aggression. We trim the small-creature removal (Dead // Gone, Sink into Stupor, Dismember) since their key threats are Solitude, Overlord of the Balemurk, and Quantum Riddler, which dodge or outsize that removal anyway. Keep Force of Negation and Subtlety at full count to fight through their Thoughtseize-backed disruption plan.
