Ocelot Pride Midrange goes wide with small Cat tokens, and Broadside Bombardiers' Boast ability lets you sacrifice a spent permanent for direct damage to snipe a Guide of Souls or an Ocelot Pride token and close races. Pyroblast and Hydroblast-style answers don't apply since this list is mono-white/red with no blue spells to target, so they stay in the sideboard. Chrome Mox is a liability against Thoughtseize and Orcish Bowmasters punishing extra cards drawn, so trimming it for more bodies is correct. Chalice of the Void at one and Trinisphere remain mainboard stars against their cheap curve of one- and two-mana threats.

Dimir Tempo is entirely blue-based with Force of Will, Daze, Brainstorm, and Ponder, making Pyroblast a premium answer that counters their countermagic or destroys a resolved Murktide Regent or Tamiyo. Chrome Mox exposes cards to Thoughtseize and is a liability against Wasteland pressure, so trimming it for reactive power is correct. The extra Eldrazi Confluence adds another flexible answer to shrink Murktide Regent or reset Tamiyo. Keep Chalice of the Void at one and Trinisphere mainboarded since they devastate the opponent's one-mana cantrip and discard suite.

Chancellor of the Annex is a weak soft-counter here since it only stops one unpaid spell and the opponent generates mana surplus easily via Lotus Petal, City of Traitors, and Ancient Tomb to pay the tax. Disruptor Flute naming Aluren, Show and Tell, or Omniscience taxes their key payoff spells by {3}, which is far more impactful against a deck trying to assemble a specific combo piece. Trinisphere and Chalice of the Void remain excellent, disrupting their Lotus Petal, Brainstorm, and Ponder mana base. Keep the full proactive creature suite since this matchup is a race to close the game before they resolve Show and Tell or Aluren.
