$83,200 in the bank and 3 trades remaining.

7th in league although its close as teams 2-7 are on 9W/4L, team 1 is on 10/3 and team 8 is on 8/5. Should easily win 2 of the last 4 matches and the other 2 matches will be close. Should I hold my trades for finals or make another upgrade to cement my chances at top 4?
