Artifacts you control have ": Add one mana of any color. Spend this mana only to cast an instant or sorcery spell."
Galazeth turns every artifact you control into a mana-producing engine that fuels a barrage of instants and sorceries. You ramp aggressively with Treasures and mana rocks, then convert that artifact mana into oversized spells, copy effects, and burn to close out games. The deck plays as a spellslinger/artifact-ramp hybrid that snowballs once Galazeth sticks.
Massive mana acceleration by tapping all artifacts for spell mana, enabling huge X-spells
Fits both artifact ramp and spellslinger shells with strong synergy overlap
Free Treasure on ETB and recastability as a commander give consistent value
Izzet has deep instant/sorcery card draw and tutors to chain spells
Mana ability only works for instants and sorceries, so it's narrow outside that plan
Heavy reliance on the commander to power the engine; removal sets you back hard
No built-in protection or evasion beyond flying
Two-color Izzet lacks efficient removal for problem permanents and enchantments
