An extremely fun deck to play, every battle is different. Good chance of winning due to wide array of monster effects and draw loops.
Mark of time
15 x Quantum Tower
2 x Shard of Readiness
6 x Shard of Serendipity
6 x supernova
8 x entropy pendulum
2 x arsenic (or any favorite weapon)
3 x improved blessing
6 x fate egg
4 x electrum hourglass
The deck may take 2-3 turns to really get moving but you use a couple supernovas, you can control any monster that may turn up through serendipity or eggs. Due to hourglasses, the amt of cards in the deck doesn't really hinder your ability to get what you need. Also, there is room for shields/additions if wanted.
