Perpetual Timepiece gives me back my lost win con's, that's why it's in there, for insurance. I know the creatures I have can die easily, meaning my cartouches can't do their thing with the Trials. However, if I have recursion in my deck to bring them back to life, it gets annoying for my opponent since they're running out of ways to kill while I just
replenish my own
supply. That's the survivability I have in mind for this deck.
