Izzet Spellementals wants to chain cheap cantrips like Opt and Sleight of Hand into discounting Hearth Elemental and Eddymurk Crab. Duress can strip a key piece of interaction (Get Out, Prismari Charm) or a payoff spell like Traumatic Critique before they can use it against your board. We don't bring in extra copies of Requiting Hex since Hearth Elemental costs 6 and Eddymurk Crab costs 7 before reduction and often aren't cast early — and they have no Elemental tokens or cheap creatures for it to target. We trim Fanatical Offering and Mutagen Man since this matchup rewards proactive disruption over slower value engines.
