This Gruul deck floods the board with colorless Eldrazi Spawn tokens and big colorless threats like Devourer of Destiny and Emrakul, the Promised End, so Fade from History is excellent, wiping their Blade of the Bloodchief and any Vexing Bauble while leaving you a 2/2 Bear. Damping Sphere punishes lands like Eldrazi Temple and Ugin's Labyrinth, causing them to produce only a single colorless mana when tapped for two or more mana. Collector Ouphe shuts off Blade of the Bloodchief's equip ability and other artifact activations, slowing their engine considerably. Cut the weaker small-impact singletons that don't affect the race against their bigger bodies; keep your full mana engine intact since you still need to outrace them to Craterhoof Behemoth.

Izzet Prowess plays a low-curve tempo game fueled by cheap spells like Mishra's Bauble, Lava Dart, and Preordain plus free pump from Mutagenic Growth, so Damping Sphere taxes their multi-spell turns and slows Cori-Steel Cutter's Flurry trigger. Vexing Bauble shuts down their Mutagenic Growth entirely since it costs no mana, denying free combat tricks. This matchup is a race, so keep your full mana base and threats intact and only trim the slowest value creatures for interaction that blunts their aggression. Prioritize deploying Devoted Druid and Leyline of Abundance quickly to close the game before their burn adds up.

Esper GenericBlink leans on Ephemerate and Flickerwisp value loops plus a wall of interaction in Solitude, Orcish Bowmasters, and Thoughtseize, none of which your artifact hate answers directly, so this plan stays light. Collector Ouphe and Outland Liberator are marginal here since the deck has few relevant artifacts, but Outland Liberator can still destroy enchantments like Overlord of the Balemurk if needed. Your best path is simply resolving Green Sun's Zenith or Nature's Rhythm into a big threat before their Thoughtseize strips your hand and Solitude exiles your creatures. Keep the core engine at full strength since removal-light swaps won't meaningfully improve this grindy matchup.
