Izzet Prowess exists in the database as a Standard archetype, but it has effectively disappeared from the current meta. Over the last 60 days it shows zero weekly trend activity and zero matches played in recent tournament data, meaning it is not showing up in competitive Standard events right now.
The current Standard meta is dominated by other archetypes. The top decks by presence over the last 30 days are Landfall (13.8%, 54.4% winrate), Izzet Lessons (11.8%, 53.6%), Dimir Excruciator (8.4%), and Dimir Midrange (7.4%). The Izzet color pair does have a foothold in the meta, but through Izzet Lessons, Izzet Midrange (5.6%, a strong 56.3% winrate), and Izzet Spellementals (4.5%) -- not the Prowess shell. The key Prowess cards in the database (Cori-Steel Cutter, Stormchaser's Talent) appear to be playing home in those other Izzet builds instead.
In short, Izzet Prowess as a distinct archetype has been absorbed or outcompeted by other Izzet strategies in the current Standard environment.
