Modern Humans by Fluorspar
If Unclaimed Territory helped Humans become a deck in Modern in 2018, then Secluded Courtyard will help solidify its mana base, giving you access to another rainbow mana effect that will also tap for colorless to let you cast Aether Vial and Dismember, unlike Ancient Ziggurat.
Flourspar is a MTGO user who constantly does well in MTGO Challenges with the most diverse Humans builds and this time reasserted themselves by getting a Top 8 finish with Upriser Renegade and Abzan Falconer!
Because of Champion of the Parish and Thalia’s Lieutenant, Upriser Renegade has the potential to attack for huge chunk of damage as early as turn three. The current build is lacking of Kitesail Freebooter and Phantasmal Image, two pillars of the old Humans lists that was more geared towards acting as prison deck rather than an aggro deck.
Thanks to Secluded Courtyard, you can even afford to play with Tourach, Dread Cantor, since you can pay for its kicker cost with Cavern of Souls and other similar lands. You’re simply replacing Horizon Canopy with Silent Clearing to always have the right mana to kick Tourach when needed.
Adeline, Resplendent Cathar has officially replaced Mantis Rider and Imperial Recruiter has become a pillar of the deck, not only able to get key prison elements like Meddling Mage, Kataki, War’s Wage or Sanctifier en-Vec in the right matchups, but also chaining itself to then one-shot the opponent with Thalia’s Lieutenant.
