Only the final map left now. Beat ?-5 with 4x 600+ speed teams and a megaslow helper.

First team had one evolved bronzie to be able to take down the first enemy + 2*s with 5-600 speed.
Second team had my best and fastest units including Orchid.
Third team had 2*s and shitty bronzies.
Fourth team again had the best things i could get at high speed.

Team 1 and 3 basically killed the first mob, then ran downwards and got themselves killed. Team 2 and 4 went up through the spiderwebs and killed the 2 thingies there with some RNG. The helper was slow and eventually killed the final boss. If you have many fast helpers you could always opt to remove the 4th team entirely and just rely on the helper teams to go through the spiderwebs instead.

Edit:
And there i finished the final map.
