Serum Powder (DST-138, Rare) is an artifact from Darksteel that can tap for one colorless mana. While in your hand, you may exile your entire hand and draw that many cards in place of taking a mulligan, an effect you can use in addition to normal mulligans. Its exile-based mulligan replacement changes how your opening hands are refreshed and interacts with effects that care about exiled cards.
