My Prirates VS enemies Murlocs - How got they so strong ?!

Greetings mortal !
HeathStone is a strategic card game, where you have to strengthen your minions and build the strongest battleground to defete the 7 enemies.
In this solo game we played with Pirates, which are able to get more attack with each attack they perform.
Sadly we got destroyed by the Murlocs from our enemy but hey 2nd place is still a looser.
Enjoy the battle !
