Izzet spellslinger deck built around Rootha, which creates a flying, hasty X/X Elemental at the beginning of combat if an instant or sorcery has been cast that turn. X is the greatest mana value among those spells, so the deck wants a big spell cast precombat. Cost reducers and spell-only mana let it cast expensive sorceries and instants early, and copy, populate and token-doubling effects multiply the Elemental. Wizard and trigger-doubling pieces make every spell and combat trigger count twice. How it wins: It casts high-mana-value spells precombat to make large evasive hasty Elementals, copies or multiplies those tokens, pumps the team with spell-triggered effects, and attacks through the air, with Niv-Mizzet and Vivi pings as backup reach. Key roles: - Big-spell fuel for Rootha: Expensive instants and sorceries that do useful work while setting a large X for the Elemental. Cards whose cost drops with board state let a high mana value be cast cheaply. (Magma Opus, Volcanic Salvo, Sea Gate Restoration) - Cost reduction and spell mana: Reducers, spell-only mana sources and ritual sorceries pay for the big spells. The rituals also count as instants or sorceries for Rootha's trigger. (Goblin Electromancer, Resonating Lute, Rapturous Moment) - Token multiplication: Populate, copy and clone effects duplicate the Elemental or turn every token into copies of the biggest one. This turns one large flier into an army. (Brudiclad, Telchor Engineer, Rionya, Fire Dancer, Determined Iteration) - Trigger doubling and spell copying: Wizard and magecraft doublers make the beginning-of-combat triggers fire twice. Copying spells adds more casts and value. (Veyran, Voice of Duality, Harmonic Prodigy, Wizard's Staff) - Spell-payoff creatures and reach: Prowess granters, storm, and growing or damage-dealing spell payoffs add pressure and direct damage alongside the Elementals. (Niv-Mizzet, Parun, Bria, Riptide Rogue, Prismari, the Inspiration) - Cheap interaction and card flow: Low-cost counters, bounce, burn and cantrips guarantee a spell is cast before combat each turn and keep the hand stocked, while protecting the plan. Token combat damage also draws cards. (Expressive Iteration, Izzet Charm, Curiosity Crafter)
