Cool!
Time shard is for mitosis or the nymph right?
I found more useful twin universe than phase spider and cloack really helps with keeping alive creatures while they are weak.
5 turns of patience is enough to kill all creatures on the spot.
One blue shard can safely be swapped for a blessing if missing, but two shards are the minimum to keep the deck working.
If the opponent is really heavy with damage CC you can even assign a guardian to the healing duty reversing his attack!
