Prophet of Distortion

The whole premise is the pip buried in the activation cost. Devoid means the card sits in the box as a colorless Eldrazi rather than a blue creature, but the draw engine is what defines it: for a single card, and that lone can only come from a source that actually makes colorless mana, not from any blue land you happen to have. It is a one-mana 1/2 that does nothing on the body, parked early to become a repeatable draw outlet only once the colorless-producing lands come online. The design belongs to a brief experiment in treating colorless mana as a resource you build toward rather than a default, where Wastes and the Eldrazi temples gated effects that would have been freely castable in any other mana base. The rate per card is deliberately slow (four total mana, one of it restricted, for one draw), but there is no tap symbol in the cost, so the ability doubles as a mana sink: a deck flooding on colorless can fire it as many times in a turn as it can pay for, converting a stalled late game into a steady stream of cards while the 1/2 frame hides behind blockers. That dual role, thin value early and a colorless overflow valve later, is the entire reason the body is so slight. Strip the out and it would be an unremarkable looter-adjacent creature; the restriction is what gives it a job.
