I was playing a game last night against T-50 deck, i don't remember which one.
I had 2 burrowed Elite Shriekers and the AI had an Otyugh I had played gravity pull on, but not killed due to its sundials. It played a fallen druid on its turn. I played a gravity pull on its druid and one of my shriekers lost the "burrowed" graphic. The shrieker was still flashing to signal it could be un-burrowed, but I left it alone. The stats were still 5/4 indicating it still thought it was burrowed. On the AI turn, its Otyugh ate my "burrowed" shrieker
