The Magic: the Gathering Strixhaven gameplay has started in the Standard format via MTGO, and one of the notable deck archetypes that got a distinguished finish in the MTGO Standard League was the one played by a good friend and fellow Ilonggo. He goes by the username air_vengeance, and he piloted a Prismari (Blue-Red) deck that was kind of a tempo build but with game-ending Dragons as its creatures.

He finished 5-0 in the MTGO Standard League and here below is the decklist. I am not currently familiar with the detailed card interactions but what I know is that the dragons act as a Treasure token source which later on used to ramp up and be able to cast the big spells. While getting there, utilized are counterspells and spot removals.
