Have 350k coins what should I do??

I am sitting at 350k coins and don't know who I should get , I started 3 weeks ago.

This is my team: https://www.mut.gg/24/lineup-builder/921733d6-a373-4780-b55a-5885fe60836c/

3 weeks, that is incredible! I would offload fitz and pick up bobo (LOVE him, same build and speed), and try to fill out your backups with 82 zcs to get that 25 zc team(it is an insane upgrade) I would also recomend picking up julius brents 6'4 fast, and try that julius peppers or carmichael card for user. Trust me you will notice the difference. Good luck!
