Underworld Circle Another last-resort card, Underworld Circle makes both players remove from play all the remaining monsters on their deck
Whenever a nonwhite creature dies, return it to its owners hand at the beginning of the next end step
Many green removal spells cause two creatures to fight each other, but this is one of the few that deals damage

Throw in a handful of dual lands and some playable utility lands like Bojuka Bog and Geier Reach Sanitarium, and counting only rare lands and other lands worth over $1, and the average value of the land slot in Commander 2019 has roughly doubled since last year, with the Sultai Morph deck clearly leading the way thanks to the Battle for Zendikar dual lands and the Jeskai Flashback deck lagging behind with a surprisingly lackluster mana base (especially considering it's a three-color deck)
