Well you got lots of unique last time you draw. The game doesn't give uniques everytime you want to draw. There will be sometimes or many times an unlucky draws next. Then lucky draw again the next day or week.
It's true that the draws are so frustrating if you don't get what you want after saving so much souls.. but it's a part of the game.
How about combine or drops? After I fail from draws I just think of other positive things like earning millions of gold and lot of stones collected along the way. And learned not to use 1,000 souls in just a day 😁
