So far, I've pulled 22 times; 2×10 and 2×1. I've pulled 1 hero card, Killjoy, the rest have been SS. I figure I'll give it another few tries then I'm done.
I got him in my 1st 10 pack and a lot of people in my guild got him in 2 or 3 ten packs. Waiting to see if they have a diamond spender event before trying for 4* or 5*.
the drop rate is nice, i got the card in the 2X10 pulls, some people got it even in the 1stx10 pull, the max limit seems to be 4x10 though since many players are claiming they got it at that.
All in all the drop rate is nice in 8000 Diamonds [100$] most whale got him to 5-6*
Finally got him, took 32 pulls. Also pulled Cara as well. So for the 30 pulls, I ended up with 3 new toons, Dalton, Cara, Killjoy. Not bad considering the price of the pulls vs CS chests & diamond.
