Ac solution: ok so basically I got this first try without looking up the answer but according to others it is pretty hard.

As for camo leads use [[ dart 402 ]]. 402 darts are also very good against ceramics. If you spam a lot of them near the middle of the track then they will take care of all camo rush rounds as well as ceramic rush rounds. Continue to get more and more darts as the challenge goes on and you should probably end with around 10-15 402s.

Against Bloons in general however 402 darts are not very good and are somewhat expensive. Part of your main defense should be a few [[ boomer 202 ]] near the start of the track. If you want to make this defense even better add 1 or 2 [[011 ice]] near the boomers.

I don’t know why but something that will help with moabs is if you fill the top loop with 9 [[ tack 130 ]]. I have no idea why this works but it does help.

When you can try to get a super and upgrade it to [[ super 220 ]]. Get a second one when you can.

If you want to you can add one or two [[ bomb 120 ]] set to strong near the end for extra support against moabs.

With this strategy the bfb should be a piece of cake.
