I tried to build a more aggressiv variant of Mono Time because I dont have most of their more expensive legendaries. It is pretty strong against most decks on Master right now. The good stats of most of your units and Infinite Hourglass help against Aggro and cards like Teacher of Humility, Amaran Armadillo or Sand Warrior are good against greedy Midrange and Controll decks.
The most problematic cards are Harsh Rule and Vara, Vengeance-Seeker. I put one Hesitate in the market to counter Harsh Rule, but i dont have a really good counter for Vara, you just have to be fast enough.
