Spell Snare mostly hits Badgermole Cub and Bitter Triumph and misses their one-mana Thoughtseize, Duress and Fatal Push, so it comes out. Volcanic Spite can't kill Sheoldred, the Apocalypse (4/5) and overlaps with Anger of the Gods against their small creatures, so it comes out too, along with one Fiery Impulse. Anger of the Gods sweeps Badgermole Cub, Graveyard Trespasser and animated Mutavaults, and it knocks earthbent lands out of creature form, though those lands return tapped. Mystical Dispute loses its discount here because Golgari plays no blue spells, so it is a full three-mana soft counter. It can still target any spell and taxes their mana by three. Lean on the removal and the card advantage from Deduce and Fable to grind through their Thoughtseize and Sheoldred, the Apocalypse. Keep Spell Pierce in since it taxes Culling Ritual and Thoughtseize early.

This is the full mirror, so the game is decided by who lands Indomitable Creativity or Fable of the Mirror-Breaker first and who counters the other's key spell. Mystical Dispute costs only {U} against their blue spells like Deduce, Prismari Command, and their counterspells, making it a far better rate than Make Disappear. Negate stops their Indomitable Creativity, Prismari Command, and Volcanic Spite outright. Spell Snare is weaker here since it only counters mana value 2 spells like Deduce, Make Disappear, and Volcanic Spite, and it can't touch Indomitable Creativity, Prismari Command, or the one-mana Fiery Impulse and Spell Pierce, so it is the first cut.

Anger of the Gods sweeps their mana dorks, Skyclave Apparition, Enduring Innocence, and Thalia, Guardian of Thraben while exiling them so they can't be recurred via Collected Company shenanigans. Chandra's Defeat is dead here since their creatures and planeswalkers (Elspeth, Storm Slayer) are white, not red, so it should NOT come in — instead bring in the second Anger copy's worth of value from trimming Spell Snare, which has limited mana value 2 targets against this curve. Spell Pierce and Spell Snare's remaining copies still help disrupt Collected Company and Archon of Emeria on curve. Focus removal on Skyclave Apparition and Archon of Emeria since both warp the game if left unanswered.
