Try the Junkz, they are really affordable and decent cards

Uppers all the way, they are cheaper than Junkz. Uppers are about 90k for the whole clan whereas Junkz are around 120k. Plus -10 opp attack min 3 is a lot more useful than +8 attack. Especially when Uppers have a lot more cards that can overpower other clans. Don't get me wrong, I love Junkz ; I just don't believe that they can compete with Uppers really. They dominate in Elo and DM, whereas Uppers are more of a DT and Survivor clan in my opinion. You could also try Bangers, as their bonus is Newbie friendly and allows an advantage against a lot of cards. They also have many solid cheap cards (Y)

I recommend working with your Bangers and Uppers.

Keep: Lucas Naykee Burt Frankie Hi and Jody.
Buy: Harold Bubbles and Chlora (You might need to grind a bit or sell cards to get Chlora)

Your deck will be quite strong, and hopefully you can win 6 or even 7 out of 10 of your games.

Sell them all except Burt and Frankie Hi and make a cheap Sentinel or Uppers deck.
For the Uppers use Burt Frankie Hi Harold Glenn Hugo Jonas Samantha and Bianca
For Sentinel use Hugo Owen or Sammy (Whichever you can afford) Katja Luis Morgan Tobbie skinner Kyle
You can also try a half deck with Uppers and Sentinel but it is very risky.
I hope this helps also stay away from Junkz they do have some good cheap cards but only enough for a half deck and there good cards are pricey. Also with the decks mentioned above don't forget to upgrade your cards when you get the chance (Kyle to Lehane, Owen/Sammy to a better 5* there are so many in Sentinel, Bianca to Wendel) All in time and clintz though
