3 rulings from Wizards of the Coast
- 1 October 2009Intimidate looks at the current colors of a creature that has it. Normally, Halo Hunter can't be blocked except by artifact creatures and/or black creatures. If it's turned white, then it can't be blocked except by artifact creatures and/or white creatures.
- 1 October 2009If an attacking creature has intimidate, what colors it is matters only as the defending player declares blockers. Once it's blocked, changing its colors won't change that.
- 1 October 2009Halo Hunter's triggered ability isn't optional. When it enters, if you're the only player that controls an Angel, you'll have to target an Angel you control.
