The recent 5K Strixhaven Championship Qualifier @ Star City Games saw two Cycling deck archetypes in the Top 4 finishers. One of which is of the Jeskai colors because having more color access is the variance of mainboard and sideboard. The notable maindeck cards are Improbable Alliance and Irencrag Pyromancer whereas for the sideboard are the counterspells Disdainful Stroke and Negate.

The deck was piloted by Tomohiro Nakagawa and the Top 4 finish was out of 337 players which is quite a huge tournament attendance.
