The rate they are going with this stuff it will probably require Relic 7 just to enter the challenge. But not relic 7 on useful characters like Finn it JTR, instead it will require Relic 7 on Rose, Holdo, and Resistance Pilot, then require some random team that doesn't make sense to fit the forcing non-synergy teams so like, KRU lead with Vet Chewy, 3p0, EP, and some other random character like Tusken Raider, all also requiring relic 7, then require something completely irrelevant to the character too, like require 7* Melevolance with a team of resistance pilots and FO tie fighter.
Then you tier 4 will be entering your credit card to unlock a special key to unlock the tier. The tier will then require you to face toons that will completely one shot your entire relic 7 team and then just claim "oh you just don't have the strategy, even though strategy has 0 to do with it since they wipe out 3 toons before you even have a turn despite at least one of your toons having 300+ speed." With a final button at the end that you can click on to re-enter your credit card for a $199.99 to instantly unlock it at 7* because content needs to be more accessible to people!
