Serum Sovereign (ONE-410) is a Phyrexian Sphinx creature. It gains oil counters when you cast noncreature spells and has an activated ability — pay {U} and remove an oil counter: draw a card, then scry 2. With flying and repeatable card selection, it functions as a spell-focused draw engine that complements control and midrange blue strategies.
