Here is one i used for 3 stars @ 1700-2000 rating
CC Lv: 8
Required Space: 200
2 (spells??? I dunno what to call them)
Troops: 3x Iron Storms
4x Medics
10x Pyros
5x Bombers
2x Air Strikes
Placement/Strategy:I place the Storms with a little space in between so they don't take splash damage ( I also take care of the most annoying mortar i can with the Air Strikes, if they are right next to each other you can destroy more that one!)... I place Bombers to try to get to the Jerichos and spread Pyros to destroy them... once they are down or low i will bring in the healers on the Storms along with the Heros.
Addtional Note: I am still working on more efficient strats, as this one is rather expensive and take quite a while to train. If you have your own ideas leave a comment!
I am lvl 85 with a 220 max army supply. To attack i usually use 10 mosquitoes 10 bombers 16 gunners and 80 rifleman, this army will take about 24 minutes to make. At lvl85 my rating usually hovers around 2200 and its a little more difficult to get 100% attack victories . So I like to drop to about 1700 rating so i can farm as much oil and gold as possible. At 1700 rating all you need is 16gunners and 80 rifles ( 10mins build time). Hence my mosquitoes are lvl2 gunners lvl6 rifles lvl5 bombers are level 5.
I use 2 iron storms 5 mosquitos 2 nurses 2 invaders and 4 air strikes. I have a level 9 command center and 220 space and it takes an hour to train but I usually get 3 stars also join my clan EPIC XUPERIA
