Ruby Storm's only creature is Ral, Monsoon Mage, so Stern Scolding has a single narrow target and gets cut, and Beyeen Veil's -2/-0 does nothing relevant against Ral. Spell Snare stays in, because their key rituals (Desperate Ritual, Pyretic Ritual) and card selection (Manamorphose, Reckless Impulse, Wrenn's Resolve) all have mana value 2, which is exactly what it hits. Into the Flood Maw is also weak against a deck that wins by chaining spells, so two copies come out. Consign to Memory can counter Grapeshot's storm trigger, Ral's coin-flip trigger, or a Ruby Medallion, and replicate lets one cast cover more than one of those. Flusterstorm taxes their instants and sorceries, including the rituals, and its own storm copies grow with the number of spells cast before it, so it is best late in their turn when they are low on mana to pay for it. This is a pure speed race, so prioritize resolving your own Charbelcher as fast as possible while holding up Flusterstorm or Counterspell for their combo turn.
