This game has a horrible algorithm. You never get the color you need on the board. You can run a combo of 10 and only get one shield the color you need. That is 30-50 Saw shields of other colors powering the other team that eventually crushes you without you getting a hit. Thought they fixed it. I was wrong. They are money hungry and make it hard to pull good heroes. 50 pulls and you get nothing. This stays a one until these problems are fixed indefinitely.
