This deck was originally going to be a sacrifice deck, I hate Fire so I thought maybe mono Shadow. But where was the win condition? Time has some interesting abilities to get small minions pumped out, good for sacrificing and just fending off a board. So with a minion swarm sacrifice deck in mind, what makes it better? Xenan Obelisk. Pillar of Amar pumping out a 7/7 each turn? Amber Ring giving you 3/3s for 3? And the deck runs more than one Obelisk so it just gets tastier. The deck is weak to extreme swarming and fliers but hopefully if you use your removal smartly and get some nice draws you can overcome at least the fliers. Novaquake Titan was added for those board vs board games where attacking would only lose board presence for the respective player. Why not just remove their board?
Conclusion: This seems to have potential and if theres something you could suggest to improve it, it'd be appreciated.
