This matchup is a race — their gameplan is assembling Basking Broodscale with Blade of the Bloodchief and Glaring Fleshraker to generate infinite counters, then closing with Walking Ballista, so you need to present lethal before they go off. Flare of Fortitude is the critical piece of the post-board plan: hold it open when swinging to protect your equipped creatures through their Pyroclasms, which would otherwise wipe Ornithopters and Esper Sentinels off the board at the worst possible moment. March of Otherworldly Light exiles key combo pieces like Blade of the Bloodchief or Walking Ballista at instant speed, and Pithing Needle naming Basking Broodscale or Glaring Fleshraker can dismantle their engine entirely before it assembles. Prioritize landing Colossus Hammer on Inkmoth Nexus for a poison kill — it bypasses their ground blockers and is the fastest path to closing the game. Trim the slower enablers and redundant tutors since your fastest draws win this matchup, not toolbox lines.

Izzet Prowess is a fast, interactive deck that will try to trade efficiently with your creatures while racing you on the board — their post-board configuration adds Hurkyl's Recall and Consign to Memory to blow up your equipment setup at critical moments. Flare of Fortitude protects your Colossus Hammer-bearing creatures from Lightning Bolt and Unholy Heat, which are their primary answers to a suited-up threat; the free activation by sacrificing a white creature is especially relevant since Ornithopter is expendable. March of Otherworldly Light answers Cori-Steel Cutter and Stormchaser's Talent before they snowball out of control, since letting those resolve and stick can make their creatures too large to race. Trim the lower-impact utility equipment (Shadowspear, Nettlecyst, Paradise Mantle) and the redundant Sigarda's Aid copies, since this matchup is won by landing a protected Hammer threat fast rather than assembling the full artifact synergy package.

Esper Blink's primary disruption is four copies each of Solitude and Fatal Push, threatening to exile or destroy your equipped creature at any moment and strand your Colossus Hammer in play. Flare of Fortitude is your most important sideboard piece here — sacrificing a white creature to grant your threat indestructible lets you push through Solitude during combat or Fatal Push in response to an equip activation. March of Otherworldly Light answers Teferi, Time Raveler, who would otherwise bounce your equipment mid-combo and lock off instant-speed plays; it also cleanly exiles White Orchid Phantom or Vexing Bauble out of their sideboard. Trim the equipment redundancy (Paradise Mantle, Nettlecyst, one Steelshaper's Gift, two Leyline Axe) since your plan is to land and protect a single threat rather than flood the board with equipment. Inkmoth Nexus infect kills are especially valuable in this matchup because poison counters bypass any life gain from Solitude and close the game before Overlord of the Balemurk or Emperor of Bones can grind you out.
