5 rulings from Wizards of the Coast
- 1 May 2007Each Imperial Mask permanent is independent and affects only its controller and the opponents of its controller.
- 1 May 2007Only teammates within the range of influence of Imperial Mask's controller will get a token. Imperial Mask's controller doesn't get a token; that player just gets the Imperial Mask.
- 1 May 2007If Imperial Mask becomes a copy of something else after the ability triggers but before it resolves, the tokens will enter as copies of whatever the ex-Imperial Mask is now. If Imperial Mask became a copy of something else and then left the battlefield, the tokens will enter as copies of whatever it was copying when it last existed on the battlefield.
- 1 May 2007This card creates tokens that enter as enchantments, not creatures.
- 1 May 2007If Imperial Mask has left the battlefield by the time the triggered ability resolves, the tokens will still enter as copies of Imperial Mask.
