Aetherstorm Roc | Creature | Bird | Flying
Whenever Aetherstorm Roc or another creature enters the battlefield under your control, you get {E} (an energy counter).
Whenever Aetherstorm Roc attacks, you may pay {E}{E}. If you do, put a +1/+1 counter on it and tap up to one target creature defending player controls. | Scott Murphy

Whenever an opponent casts a spell, if it has a single target, change the target to enchanted creature if able. | Tyler Jacobson
