Devoid doesn't affect the color identity of the card for the purposes of the Commander variant. For example, while Abstruse Appropriation is colorless because it has devoid, its color identity is still white and black, and it can't be included in a Commander deck where the commander's color identity doesn't include both white and black.

If a card loses devoid, it will still be colorless. This is because effects that change an object's color (like the one created by devoid) are considered before the object loses devoid.

Devoid works in all zones, not just on the battlefield.

Eldrazi Repurposer's triggered ability will resolve before Eldrazi Repurposer does. If Eldrazi Repurposer is countered or otherwise leaves the stack in response to that triggered ability, the triggered ability will still resolve as normal.
