Esper Control is one of the most hostile matchups for Ruby Storm — their main-deck Orim's Chants can lock your combo turn outright, and Isochron Scepter (likely grabbing Orim's Chant post-board) creates a hard lock you must answer before attempting to win. Bring in your own Orim's Chants to cast on their draw step, buying yourself a completely free combo window where they cannot cast Counterspell, Consign to Memory, or Orim's Chant in response; Prismatic Ending handles Teferi, Time Raveler and Isochron Scepter at sorcery speed, while Wear // Tear answers both at instant speed and also hits Chalice of the Void coming in from their sideboard. Cut Artist's Talent entirely — it is a two-mana enchantment that Teferi bounces for free and Prismatic Ending destroys, and it requires a full turn to pay off against a deck full of interaction. Trim Glimpse the Impossible (the spirit-token plan folds to Supreme Verdict and Wrath of the Skies) and shave Flashback and Valakut Awakening to slim the non-ritual, non-cantrip slots — your goal is to find a single clean window with a chant in hand and enough mana to go the distance in one turn.

Boros Energy's most dangerous post-board piece is Drannith Magistrate, which shuts off Past in Flames, Flashback, and Ral's exile-cast ability all at once — Prismatic Ending is essential removal to answer it on the spot. Orim's Chant is your best protection tool: cast it on your combo turn to prevent them from responding, or tap it on their turn to buy a critical extra turn against their aggressive clock. Wear // Tear answers Vexing Bauble, which otherwise taxes your free spells and can shut down the storm chain entirely. Trim the slower, higher-redundancy draw spells (Valakut Awakening, Glimpse the Impossible, Artist's Talent) and the Wish package, since your sideboard interaction is already in the deck and Wish's flexibility is less valuable when you're also boarding in specific answers. Prioritize a fast, clean combo line — ideally resolving before they can stick a Magistrate — and use Orim's Chant to clear the way on the turn you go off.

Affinity is a race — their clock is fast, but post-board they become a disruption deck with Consign to Memory, Mystical Dispute, Vexing Bauble, and Grafdigger's Cage all threatening to strand your combo. Orim's Chant is your best tool here: cast it on your combo turn to blank their entire interaction window, preventing Metallic Rebuke, Consign to Memory, or any other instant-speed answer. Wear // Tear handles the permanent-based hate, cleanly answering Grafdigger's Cage (which shuts off Past in Flames and Flashback), Vexing Bauble, and Engineered Explosives before they can disrupt your setup. Empty the Warrens provides a graveyard-independent kill for games where Grafdigger's Cage resolves and you can't immediately answer it — even a modest token army is often enough against a deck that trades life for card advantage. Trim the slower value spells (Artist's Talent, Flashback, Valakut Awakening, Glimpse the Impossible) since this matchup rewards explosive speed over incremental card advantage.
