Unable to solve Foundation SBC - Bronze players needed.

Hello everyone,  I am facing a challenge.

I have completed all Foundation SBCs except for "Foundation V - Advanced attack". 

I can't solve the SBCs without investing real money. I don't want to do that as it is an RTG account.  

I can't buy and/or sell players on the transfer market on PC. I realize that I can't use the transfer market via mobile yet. But on the PC, the market is only available once you have successfully completed the Foundation SBC. 

 There are currently no other SBCs that bring bronze players as rewards.  

Question: How should I solve the SBC? Paying money is not an option.  

Thanks in advance.
