During a bot game I attempted to blink a creature and it caused my game to stop responding. The creature in question was a token copy (via helm of the host) of the mutation stack containing Titania, Protector of Argoth and Vadrok, Apex of Thunder. It is also important to note that my library currently contains several hundred cards (mostly P9) that were conjured there by an oracle of the alpha. Additionally the original Titania/vadrok pile has several equipment attached to it, embercleave and a couple of swords of this and that.
