Ruby Storm

Ruby Storm uses its namesake card, Ruby Medallion, and Ral, Monsoon Mage, to cast large swaths of Red Instants and Sorceries in one turn. With Seething Song as your best way to produce additional mana alongside Birgi, God of Storytelling, Wrenn's Resolve, and Reckless Impulse keep the cards flowing. These turns culminate in either finding Grapeshot to kill your opponent or using Wish for any number of useful tools to ensure your victory.
