Izzet Phoenix is extremely spell-dense (Consider, Opt, Sleight of Hand, Treasure Cruise), making Magebane Lizard a house that punishes nearly every turn they cast multiple cheap cantrips. Scorching Shot kills Arclight Phoenix (3/2) cleanly and can also answer Picklock Prankster. Monstrous Rage is weak since their Fiery Impulse and Lightning Axe answer the enchanted creature easily, and some Kumano Faces Kakkazan come out in favor of more proactive interaction since the incidental damage matters less than disrupting their graveyard recursion plan. Consider that they may have Redcap Melee and Ledger Shredder in their own sideboard, so don't overextend into open mana.
