(As this Saga enters and after your draw step, add a lore counter. Sacrifice after IV.)

I, II, III — Until your next turn, whenever you cast an instant or sorcery spell, target player mills cards equal to that spell's mana value.

IV — Draw a card. If a graveyard has twenty or more cards in it, draw three cards instead.
