While we did see a marked decline in the win rate of Four-Color Ramp after the banning of Uro, Titan of Nature's Wrath, particularly against red and green aggressive decks and Blue-Black Rogues, Omnath ramp decks continue to have a warping effect on the metagame. The two most popular decks in the Standard metagame, Four-Color Ramp and Four-Color Adventures, both feature Omnath, Locus of Creation as a key component. Observing ladder play and tournament results over the following weeks, as well as the field of the Grand Finals over the weekend, we've concluded that additional changes are necessary.
With last month's Standard banned and restricted update, we highlighted that we'd continue to monitor the Standard metagame as well as Omnath, Locus of Creation decks and would make further changes if necessary.
