Aligned Hedron Network 
Artifact
Battle for Zendikar Rare
When Aligned Hedron Network enters the battlefield, exile all creatures with power 5 or greater until Aligned Hedron Network leaves the battlefield. (Those creatures return under their owners' control.)
The last hedron slotted into place, locking Ulamog in an infinite loop of binding energy.
