So far around 55% winrate on approx 300 matches. Pretty good! Just hit diamond (America server)

My only feedback would be that it uses coin too poorly (coin heropower always) and that it uses the opponent Mana burn skill very poorly too (it should be very prioritized when you have board control and high pressure on opponents HP/potential lethal the following turn if he doesnt board clear)
Also it does not calculate properly the extra +1 +1 gained from that pirate unit, whenever a pirate attacks give it +1 +1, so it will use a 3-3 to kill a 3 hp 3 atk unit, instead of a 2-1 to kill it for example.
