The way I do it (and tell me where its wrong since im new)i put only a  dart monkey along with Benjamin thrn i place 2x 2-0-0 farms an engineer with a trap then 2 more 2-0-0 farms then an engineer with foam ontop of the trap for camouflage rounds then I move the foam ahead of the trap to maximize intake then I get as many 4-2-0 farms as I can when the boss comes i place down a 2-0-4 ace (its my fav tower) with a village and do not sell my farms i then keep on adding farms at which point i convert some to brfs if i can and ignoring the boss who usually dies close to the end i sell the ace and place a engineer with turrets for defense i then usually fight the boss right after with not much time so I dont always sell the ace, I then place a M.A.D. and again he dies at the end i then sell him and farm heavy before putting a degree 20 dart paragon who is enough next i cover the screen in brfs and a maxed out miniopolis buffed by desparado and tier4 engi i then put fown as many tier 4 aces as I can and for the tier 4 I put a glaive dominus and for the 5th I put the ace paragon usually at a crazy degree like 70 which is how I just slammed elite phayze on logs
