Temur Indomitable Creativity's entire game plan hinges on resolving Indomitable Creativity itself or huge top-end like Atraxa, Grand Unifier and Valgavoth, Terror Eater, making Disdainful Stroke a premium answer that stops the key spell outright. Brazen Borrower doubles as a flash flyer to race and an Adventure that bounces a problematic Fable of the Mirror-Breaker token or a landed threat before Indomitable Creativity can find it a home. Lightning Axe is awkward since their best bodies (Atraxa, Valgavoth) dwarf 5 damage or are already gone by the time it matters, and discarding a card to a control-ish opponent who out-cards you with Deduce and The Theorist, Jace Beleren is costly. Proft's Eidetic Memory is too slow against their interactive, countermagic-heavy configuration. Keep the full Fiery Impulse and burn suite to pressure their low-toughness creatures like the Goblin tokens from Fable of the Mirror-Breaker.
