Temur Indomitable Creativity wants to resolve a big payoff off Indomitable Creativity or Fable of the Mirror-Breaker and protect it, so cheap interaction that stops their key spells is more valuable than slow bounce. Change the Equation can counter Indomitable Creativity itself at mana value 6 or less, or hard-counter their cheap cantrips like Deduce and Jwari Disruption's spell side. Combustion Technique can exile whatever creature they cheat into play before it attacks. Voldaren Thrillseeker and Boomerang Basics are too slow and don't interact with their combo-ish plan of cheating a big threat into play.
