Current MTG design doesn't have a required mechanical component for creature types, and generally bend towards lore and planar design. There is some space to argue that some type of life total manipulation could be tied into the Cleric type, but only 30/63 of the recent Clerics reference some form of increasing lifetotal.

As Rajul was a medical pioneer for the Atherborn, the Cleric type makes lore sense for this particular card file, with it's slot being part of the "Kaladesh" aligned 5 color EDH deck.

Cleric? Not Artificer?

Lacks mechanical cohesion.

The idea is to have two cycles with accomplice that are mono-colored. A vehicle cycle and an equipment cycle.

You caught the card mid update while I was moving some notes over from two other sources.

But does accomplice let you play this as your commander? Because right now, it's not a creature so it's not a legal commander, and accomplice doesn't do anything on this card

Extort has no color identity, as the mana requirement is in parenthesis, meaning it's not part of the card itself.

Remind me: How does extort interact with color identity?
