Tournament raid tiles

Why are there so many blue tiles in the tournament with no blue heroes allowed? I understand that you need to put in blue tiles but at least decrease it’s occurrence. Geez five raids in a row two blue diamonds in one with more blue tiles popping up. Then third attack was nothing but blue and green. Just for fun cause I was already dead practically I did a green diamond Yeap more green tiles. Fourth attack finally got yellow and purple tiles so i won. Fifth attack back to green and blue board what gives?
