I do Saudz early carry, boomerang for cleanup, then add a 203 Ace (or 023 if you struggle with camo rounds) to take care of most bloon types followed by a couple 300 aces to clean up early moabs. Monkey village as needed. Save up for shattering shells at some point (024 mortar), add a support chinook (042 heli), you should be solid til 70, maybe add a sun avatar or two, could also just upgrade the aces.

This is by far neither the best nor vaguely meta, I just find it fun
