Deciduous mechanics seek to change Magic: The Gathering forever
Wizards of the Coast is putting a new spin on Magic: The Gathering’s evergreen keywords and mechanics, expanding design possibilities through Deciduous keywords and mechanics instead.
Older MTG mechanics that aren’t featured in a Standard-release set have randomly appeared in the last few set launches. Cycling, for example, appeared in Strixhaven on the Triome land cards, but the mechanic wasn’t present on any other cards from that set. Within the Phyrexia: All Will Be One (ONE) set, both Affinity and Flashback are making random appearances despite the main mechanics being Toxic, Oil counters, For Mirrodin!, and Proliferate.
