I just upgraded my first deck and added Shard of Freedom , a fast rush Mono-Air with a good creature control.
Don't hope a 100% win rate, but it's quite high , except when the AI got very useful cards.
The average time to kill this AI with this deck is 1:15.
I have spent a lot of time fighting against it and the win rate is around 85%, i won 85 games and the AI only 15.
I wanted to use the simulator but it can't recognize "7nq" (Shard Of Freedom) that isa very good offensive and defensive card for this mono.
