ISO-8

I would be more likely to buy ISO-8 power ups than anything else on offer.

Sweet! You are also more likely to open a 5 star colossus then a champ you want

thought the last ISO-8 promotion was a bit limited and should be on offer more often with more options to buy the ISO-8.

Would like to buy or play for some ISO-8 on the game.

You get ISO 8 questing, and quest crystals.

Also dupe champs will get you some.
