Well I just had the unluckiest experience with the game yesterday.
Our alliance does SA every alternate week. So I always get hyped because we save up crystals for one entire week. This time i also had a 5 star crystal to open. I spun it with great hope. The reel starts spinning. Sparky appears in the real and spins out into oblivion. I see a Quake but she goes away too. Then Ghost Rider appears, but even he decides not to join my roster. Finally the crystal stops. Aaaaand .....its a Colossus.

I was pretty bummed about it but i guess Kabam was happier to give me an ass champion than i was sad to get him. The total happiness in the world increased so whatever.
I was really angry so i just decided to do my war attacks. You wont believe, but midway into the fight, the game lags and i lose. i am totally furious at this point and decide to open my 4 star crystal. NO luck even this time. I dupe my Yellow Jacket once again. This just means extra Science ISO and I have no Science champs to upgrade.
I have opened 25x 4 and 5 star crystals. 0 god tier champs. 1 demi-god. Pray for me friends. 1 prayer= 1 god tier champ for you and me.
Also, I would like to hear what has been your luckiest and unluckiest experience with the game.(I would have shared my luckiest moment too , but i have none).
