This opponent's engine runs through Urza's Saga, Eldrazi Temple, and colorless artifact synergies with Glaring Fleshraker and Basking Broodscale, so Meltdown blows up their Constructs and cheap artifacts. Tormod's Crypt strips Malevolent Rumble graveyard value and can hit key recursion pieces before Emrakul gets cast. Cut the marginal combat tricks since this matchup is a race decided by disruption and speed, not combat math. Keep the low curve intact and try to close the game before their ramp into 13/13s and 6/6s takes over.

This is the true mirror match, decided by who removes the opponent's early threats and closes fastest. Unholy Heat is efficient removal for their Dragon's Rage Channeler and Monastery Swiftspear, dealing 2 (or 6 with delirium) which cleanly kills both. Spell Snare snipes their Cori-Steel Cutter or Expressive Iteration for a great tempo swing, while Assault Strobe can end games out of nowhere by giving a Prowess creature double strike. Trim the combat tricks since removal and proactive damage matter more than pump spells in a mirror where both sides are racing.

Esper GenericBlink is full of small, relevant creatures (Orcish Bowmasters, Phelia, Flickerwisp, Emperor of Bones) that Unholy Heat cleanly answers, especially once delirium turns it into a 6-damage kill spell. Spell Snare cleanly catches their two-mana staples like Orcish Bowmasters and Phelia, while Spell Pierce taxes their Ephemerate, Thoughtseize, and other key noncreature spells when they're tapped out fighting through our clock. Mutagenic Growth and Violent Urge are combat tricks that do little against a deck full of removal and flicker effects rather than combat math, so they come out along with a Lava Dart whose 1 damage rarely matters here. Keep the full core of Dragon's Rage Channeler, Monastery Swiftspear, and the burn suite intact since the plan is to race before their card advantage engines take over.
