When Sage's Reverie enters the battlefield, draw a card for each Aura you control that's attached to a creature.
Enchanted creature gets +1/+1 for each Aura you control that's attached to a creature.
11/24/2014 An Aura doesn’t necessarily need the enchant creature ability for the abilities of Sage’s Reverie to count it. For example, an Aura with enchant permanent that’s attached to a creature will count.
11/24/2014 Count the number of Auras you control attached to creatures as the enters-the-battlefield ability resolves to determine how many cards to draw. This will include Sage’s Reverie as long as it’s still on the battlefield at that time.
