Veil of Rok'n

Mill X: For each creature placed in your
graveyard, add {w}{r} to your mana pool.
(Where X is 1 to 5 cards.)
Red, and gold, and green, and blue, Into the
night, up they flew. Candles lit with faith they
burn, Bringing truths to souls that yearn.
Rok'n shared all he could tell, Until at last
death's veil fell. — Aralian children's rhyme
