Mono-Green Eldrazi wants to curve into Devourer of Destiny and Emrakul while Ancient Stirrings and Malevolent Rumble dig for colorless threats, so Wrath of the Skies lets us sweep their board of small permanents and creatures for a reasonable energy payment while leaving our own Overlord of the Balemurk and Phelia (often protected or recast) less exposed. Consign to Memory snipes their colorless spells (Devourer, Emrakul, Eldrazi Spawn-generating abilities are not spells so it won't hit those triggers, but it does stop colorless creature spells like Devourer of Destiny or Sowing Mycospawn on the stack) and any triggered abilities they rely on. Ephemerate and Flickerwisp are weaker here since their best blink targets (Solitude, Flickerwisp itself) don't line up against a grindy ramp deck without much relevant removal to dodge, and we'd rather have sweepers and bounce. Keep Thoughtseize and Fatal Push in to strip or kill their key pieces before they resolve.

This is a glass-cannon combo deck built around Basking Broodscale plus Blade of the Bloodchief making infinite colorless mana and Spawn tokens, so our plan is to kill Broodscale or strip Blade before the loop starts; Thoughtseize and Fatal Push (both already maindeck) are our best tools and stay in unchanged. Consign to Memory can counter the many colorless spells this list plays off the top (Devourer of Destiny, Sowing Mycospawn, Eldrazi Temple-fueled casts) and can even stop an Eldrazi Spawn token being sacrificed... no, Spawn sacrifice is an activated ability not a spell, so Consign only hits their colorless spells and triggered abilities, not the mana ability itself — still useful against their backup big-mana plan. The extra Swamp smooths our black sources since Thoughtseize and Fatal Push are our premium interaction here; Quantum Riddler is too slow against a deck that can go off before we're pressured to race.

Izzet Prowess is a low-curve tempo deck full of cheap colorless-costed burn and cantrips; Consign to Memory stops their colorless spells like Mishra's Bauble and can even double up via replicate against two Baubles in one turn. White Orchid Phantom is a 2/2 flier with first strike that blocks their Dragon's Rage Channeler and Monastery Swiftspear profitably while also blowing up a nonbasic land (hitting their fetches or dual lands) to slow their mana. Quantum Riddler is too slow and dies to their cheap removal before it can attack, while Witch Enchanter's artifact/enchantment destruction is low-impact against a deck with few relevant permanents to hit. Our Fatal Push and Orcish Bowmasters remain excellent against their low-toughness creature suite.
