Over the past months, Once Upon a Time has become one of the most played cards in Modern, contributing to several of the most popular and highest winning decks. The consistency provided by Once Upon a Time allows these decks to much more reliably enact their early-game plan compared to other archetypes in the metagame, leading to less divergent gameplay paths. Going forward, Once Upon a Time poses a design constraint in making it too easy to assemble creature- and land-based combinations. In order to facilitate more varied gameplay and mitigate future risk, Once Upon a Time is banned in Modern.
