Uro, Titan of Nature's Wrath
This card is so good that it will see play in every single MtG format that allows mythic cards, including Pioneer.
Uro has all the markings of a broken card, but not as bad as Oko, which finally got banned from all the formats except Legacy, Vintage, and Commander. This means that Uro will definitely find its place in most decks that run blue and green.
Uro, Titan of Nature's Wrath will be especially good in Simic Ramp that runs Growth Spiral and Banefire, as well as in Sultai Dread Presence.
