Brand the Guildpact

As long as Brand the Guilpact remains in play, whenever a player taps or untap a permanent, or activate an effect, or plays a spell, you can pay {1} to counter it, and for the rest of the turn that permanent is not available for any interaction
by the controller.
Using the Dreamlands connection with his Eldritch Woods on Shadowmoor, Ashiok branded new Guildpacts from a rare dream of the distant past of Ravnica, salvaged from the mind of his very maker, the still living Azor.
