Rationale

Mox Opal was banned in Modern due to its function as a powerful accelerator and enabler for aggressive, sudden-finish strategies. The card contributed significantly to high-speed, explosive combos, one-turn victories, or opponent lockouts, especially within artifact archetypes. Given its potential to rapidly destabilize the metagame and its historical tendency to cause balance issues, it was banned to maintain overall format stability.
