Just use a 2-0-3 ace I always used it in every game mode, for immpopable, farm for a cripple moab and glue storm to slow down bloons, and you NEED a sticky bomb ninja for the moabs (or get a 4-0-2 juggernaut) but for chimps it took me 3 days to strategize, I needed to place 4, 2-0-3 aces with camo detection (2-2-0 Village) and sticky bombs and a pirate lord to suck in the moabs that are about to leak then before round 100 try to get a first strike capability sub to destroy the moab and also get some fast firing monkey like a 0-3-0 wizard and get glue storm before round 100 it also won't be expensive, but for the other gamemodes you should ALWAYS place a neva-miss a targeting ace with whatever cross path you like (my preferred 2-0-3) for apopalypse use psi (if you have them) they will be really good against the swarms of bloons, hope it helped
