Mono time is a fun consistent deck. New Dino is the nuts.
Some Tips:
Always be careful of walking into combat tricks against aggro decks. The deck has healing so you can take a few hits before you are forced to chump.
Against Justice control decks, NEVER play into harsh rule. The deck has a good amount of card draw and value. So as long as you don't throw units away, you can keep up the pressure and never let them stabilize.
Xenan Obelisk is one of the best cards in the deck, which is why one of them is in the market to make getting it a lot easier.
The rest of the market is not that thought out, but SST needs his scarf (also is a great counter to Valkyrie Enforcer silencing SST).
