Birgi, God of Storytelling // Harnfel, Horn of Bounty [Kaldheim]

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. “This is a tale to make all of Kaldheim tremble…”

Discard a card: Exile the top two cards of your library. You may play those cards this turn. Like her well of stories, Birgi’s horn never runs dry.
