Miku, Goddess of Musicals

Whenever you cast a spell, add {r}. Until end of turn,
you don't lose this mana as steps and phases end.

Creatures you control can boast twice during each of
your turns rather than once.

"In the blaze of her performance, the stage alights with passion and melody, each note a fiery testament to her eternal symphony."

(Birgi, God of Storytelling)
