Izzet Phoenix wants to go wide with recurring Arclight Phoenix and chip in with Picklock Prankster, so Redcap Melee is excellent, killing Phoenix outright and answering Picklock Prankster or their sideboarded Ledger Shredder. Abrade is flexible instant-speed removal that also answers any artifacts they bring in. This is a race where your own prowess creatures need to close fast, so cut the lower-impact Boomerang Basics and Monstrous Rage for harder removal, and Spell Pierce is weaker since Phoenix decks often have mana up to pay the tax once they're casting their third or fourth spell. Keep your full cantrip package to find action and keep up with their card advantage engines like Treasure Cruise.
