The ability is a mana ability, so it is played and resolves as a mana ability, but it can only be played at times when you can play an instant. [bethmo 1999/11/17] Yes, this is a bit weird, but it does mean that this ability does not go on the stack and cannot be countered. [D'Angelo 2007/08/23]
You can discard a hand of zero cards to use this effect. [Duelist Magazine #16, Page 28]
