I think the chances got increased (whether a bug or not) last update. Before this update the chances of what you got (according to our best guesses, we don't actually know) is 0.01% (half the chance of getting Punisher from an arena crystal or the 4-5 gem in the metamorphasis crystals). I recently also got 2 iron fists from 10 crystals so I'm pretty sure the odds got changed.
Been playing this game 10 years and still don't even have the 3*…
Been playing a long time (does anyone know how you find out when your account started?) and don’t have him at any rarity.
I do have several hundred 2*, 3* and grandmaster shards that I might get around to opening one day so you never know. He might eventually turn up.
So I’ve just opened about 40 max sig crystals of various types I had kicking around and nada. Im not convinced the odds have changed at all.
you can look in the app store or Play Store and see when you downloaded it, I think. Or look back at purchase history for when you first bought anything if you've spent. Or if you're on Android and have achievements turned on in Play, you can look at the achievements, they're dated.
wow I’ve never seen that!
Found it thanks! Almost 8 years as it turns out.
