I am never lucky with the event souls and this time is no exception. Got nothing but 3* dupes from the free 16 souls for completing challenges. Since I want the gunner derby demon, I ended up buying another 16 souls for ironite.
Opened them all at once and I was exited to see red eyes, only to be disappointed to see clansman Eddie and sentinel pyro.... I did open 2 mythical gunner souls and secured IME, but what I really wanted was the gunner convict. So I am still in the dilemma whether to buy more souls or not?
On the bright side I was able to secure my first set of primordial. So the event was Not a total disappointment for me.
Edit: changed gunner convict to gunner derby demon
