Who do I replace for Wonder Woman Regime in Injustice Gods Among Us?

Alright, I've got Injustice on the Iphone, and my triple silver team is deathstroke level 25, sinestro level 24, and knightfall bane level 24. I just got Wonder Woman Regime and i was wondering who i should take out of my team for her. Also I'm at the doomsday battle, and I've done every single battle up to that one, so that's why I was wondering, also each one of my team members has each one of their super moves upgraded 2 times, should i upgrade more or wait, i wait then till when?
are the levels of my team members good?
Is my team up to this point good?
Did i maybe get my first golden card to late? Please do tell
Also, I'm really sorry, but umm, I've heard that you can unlock Knightfall Bane, if you rate it when that pop up appears, and I always press remind me later, but just in case, how do you do it on like someone else's phone wit the account?

Sorry, about the essay i just wrote her, but I really need some help from an expert

  • Where can I find cheat codes for injustice gods among us for kindle fire? I'm trying to hack the game injustice gods among us on my kindle fire and I can't find anywhere where I can do that.

  • Injustice on iphone or ipad? Advice? I now have the game on my iphone. I don't want to put any money into the game, so I need to put my credits I earn to good items. If I save up enough for one good character, who should I get? Also, what is the best way to earn credits? By that I mean the quickest amount. Moreover, should I attempt to get the gold booster pack, the rare one is only 75000 now.
  • Injustice IOS iPhone app In the game I removed all the members on my team by dragging them down and then I exited the app. Now when I press Play and try to go to a level it crashes. I think this is because I don't have any members on my team, but I don't think I can edit my team without going to the battle screen. Is there a way that you can edit your team without pressing Play and going into a level? Yes I tried the tutorial, still crashes.
