Sorry for the necromancy and all that yeah, yeah.
Zen is a very fun and powerful deck. Playing around with unupped shards (since I don't have 6 upped SoVs), yet it's still able to net wins quite nicely. I personally used an arsenic and also added a mirror shield. Sadly, with so much SoFo, it's not as powerful as I'd like it to be, and the fact that PAs are very troll don't help. Still, great deck that I only now got to trying out. Another option would be to use sundials to stall, and that is pretty powerful, as evidenced to a 13-0 arena deck.
