Izzet Aggro mixes prowess threats with burn and Stormchaser's Talent tokens, so Clarion Conqueror is a 3/3 flier that flies over their ground creatures and blocks well against their small attackers. Beza can gain 4 life against their aggressive clock when they're ahead on life, and it can also create Fish blockers or draw a card if they control more creatures or hold more cards in hand than we do. Thalia does tax their many noncreature spells, but her 2/1 body dies to any of their burn spells, and she also taxes our own Collected Company and Elspeth, while Badgermole Cub's 2/2 body is outclassed by Screaming Nemesis and their burn spells. Lean on Skyclave Apparition to answer Screaming Nemesis or Stormchaser's Talent itself before it snowballs, keeping in mind it can't exile the Otter tokens the Talent creates.
