Trogon Forest

Trogon Forest enters the battlefield tapped.
When Trogon Forest enters the battlefield, each player creates a 0/1 green Bird creature token with flying and "{t}: add one mana of any color
to your mana pool."
"The display was like nothing I ever seen. The sky filled up with tens of thousands of birds of all colors of the rainbow. They flew like waves in the air forming a magical dance."
