Izzet Spellementals reduces the cost of Eddymurk Crab through cheap spells, but most of their support creatures (Sunderflock aside) die to a 2-damage sweeper before they get out of hand, so Pyroclasm is strong early. Voice of Victory denies them Spell Snare, Get Out, and other cheap interaction on our turn, letting our threats resolve cleanly, while Origin of Metalbending can save one of our key creatures from their removal suite. Lost in the Maze taps down only a couple of their many threats and North Wind Avatar is too slow against a tempo-oriented opponent, so both come out along with the weaker damage mode of Prismari Charm. Watch out for a fast Eddymurk Crab or large Hearth Elemental and prioritize removing them.

Mono-Green Landfall relies heavily on Earthbender Ascension and the land Ba Sing Se to power up its board, so Origin of Metalbending gives us a clean way to blow up Earthbender Ascension, denying their scaling plan. Voice of Victory prevents their few instants like Royal Treatment from saving creatures against our removal on our turn. Lost in the Maze and Prismari Charm's small damage mode are weak against a deck built around big, hard-to-kill creatures like Mightform Harmonizer and Icetill Explorer, so they come out for more targeted answers. Since this is a straightforward green ramp-and-go-wide deck without much interaction, focus on stabilizing the board and resolving our own late-game threats.

Jeskai Control wants to answer our threats one-for-one with Pyroclasm, Day of Judgment, Fire Magic, and Sear while refueling with Stock Up and Jeskai Revelation, so we bring in Spider-Sense to counter their key instants and sorceries (including Jeskai Revelation and their sweepers) and Voice of Victory to shut off their instant-speed interaction entirely on our turns. Lost in the Maze and North Wind Avatar are too slow or too reactive against a deck without a proactive early clock, and Prismari Charm's damage modes are weak against a control shell with few small creatures. Omni-Changeling adds a flexible late threat that dodges their narrow removal suite. Focus on resolving Omniscience or a big threat through their counterspells and use Spider-Sense to protect it from Jeskai Revelation.
