This loop transforms a coordinated dragon-and-warrior assault into an unstoppable sequence of extra combat phases, fueled entirely by the aggressive synergy between Radha, Heir to Keld and Savage Ventmaw. When both creatures declare an attack alongside Hellkite Charger, their triggered abilities pour an abundance of red and green mana into your pool, easily covering the steep {5}{R}{R} cost demanded by Hellkite Charger's activated trigger. Because Savage Ventmaw carries a beneficial static property that lets unspent mana persist through steps and phases, you never have to worry about your resources evaporating between steps. With every single combat phase successfully untapping your entire attacking force, you can repeat this glorious offensive infinitely across formats like commander, legacy, modern, oathbreaker, and vintage.
