* Cards with the Aura subtype don't change the zone they are in, if there is no

* valid target on the battlefield. Also, when entering the battlefield and it

* was not cast (so from Zone != Hand), this effect gets the target to whitch to
|
|
* attach it and adds the Aura the the battlefield and attachs it to the target.
|
|
* The "attachTo:" value in game state has to be set therefore.

* If no "attachTo:" value is defined, the controlling player has to chose the
