Ruby Storm wants to chain rituals (Desperate Ritual, Pyretic Ritual) and card advantage spells (Manamorphose, Reckless Impulse, Wrenn's Resolve) into a lethal Grapeshot or Past in Flames turn, with Ral, Monsoon Mage discounting the whole plan. Spell Snare is excellent, hitting their two-mana rituals and card-advantage spells like Desperate Ritual, Pyretic Ritual, Manamorphose, Reckless Impulse, and Wrenn's Resolve to disrupt their mana chains. Consign to Memory does not counter their spells directly since almost everything they cast has mana spent on it, but it does stop any free-cast interactions and colorless permanents if relevant; its main value is more marginal here, so weigh toward Spell Snare as the premium answer. We trim reactive creature-combat cards like Thraben Charm, Ephemerate, and Starfield Shepherd since this matchup is decided by disrupting the combo turn, not board state.
