You got your hero, you think… clearly I need to go with this type to win. I need this minion and it’s done.
Nopes. You will not see the one minion you are looking for, no matter how many rerolls, no matter if it is duos.
But ON THE LAST ROUND before you are going to lose, what a surprise, it shows up. ALWAYS. It is so obvious and predictable that it no longer surprises me. This is not RNG.
The game is rigged.
