Qu, Bio Manipulator

Eminence — As long as Qu is in the command zone or the battlefield, colorless creatures you control have Ingest.

Other Eldrazi you control get +1/+1.

When Qu enters the battlefield create X 0/1 Eldrazi creature tokens with "Sacrafice this creature: Add {c}" where
X is the number of cards in exile.

If Qu is your commander your deck may include cards from all colors.
