Jawa Challenge

Here I am in this forum again. Galac Challenges have been a grind lately for me. More so than I remember in the past. While it is recommended that I attempt level ix, I have barely been able to finish level vii. The stronger my team gets, it seems that the worse I do in these Challenges.

Anyway, does anyone have any counters for Jawas? I have 4.5 GP but can't do anything past level v. By level vi, I'm all blown up within 20 secs while Jawas keep regenerating protection.
