This card is blue in all zones. See Rule 402.8a. [D'Angelo 2007/06/04]
Since this card has no mana cost, it cannot be played as a spell. It can only be played using the Suspend ability. [D'Angelo 2006/10/08]
It can be played if an effect allows you to play a spell without paying its cost. See Rule 203.1b. For example with Mind's Desire. [D'Angelo 2007/10/20]
