Any tips for my hangar?

So I've recently changed up my hangar, so I wanted to see if anyone would give tips on how to improve. P.S., I know that things need to be upgraded, it's just that I leave my iPad at home so most things finish upgrading when I'm in school.


I run:
Aphid Taran Griffin (7 bot level/6 + 5 aphids/6 tarans)

Thunder punisher leo (6 bot level/7 thunder/4 punishers)

Magnum Stalker (level 5 for bot and mags)

RDB Griffin (7 bot level/5 pins/6 tulus)

Im planning on swapping out my leo for a thunder Carnage (I have 2 level 7 thunders).

Anyone have any tips for my hangar? I just purchased my second aphid for the Griffin so I am rather low on gold, just keep that in mind when posting.
