Domain Zoo's early creatures like Psychic Frog start at 1/2 (though it can grow by discarding cards) and Territorial Kavu scales with domain but is still vulnerable early, so Searing Blaze is efficient two-for-one removal plus reach, especially with landfall online. Exquisite Firecraft's uncounterable clause with spell mastery matters against their Stubborn Denial. Eidolon of the Great Revel is too risky against cheap removal like Fatal Push, so it comes out. This is a straightforward aggro mirror where efficient removal and reach outweigh a symmetrical damage engine.
