Aqua, the Forgotten Master

Shroud, first strike
Whenever you cast a noncreature spell, Aqua, the Forgotten Master gets +2 +1 until end of turn.
{1}{b/g}{b/g}: Return Aqua, the Forgotten Master to the battlefield tapped and attacking.
The endless dark abyss slowly consumes what hope Aqua has left, staining her heart with fear and shattering her resolve. It's simply a matter of time before she becomes one with the darkness.
