Use dragg attack !... It can take down maximum th8 bases....
Composition 9 dragg , 3 loons , and 4 archers with maxed loons in cc , with haste spell ....
Spells: 2 lightning, 1 eq , and 1 rage
Strategy : release 2 lightning spells and the eq on the ad just in front of the sweeper !...
Then release your cc loons , at the back of sweeper from the wizz tower side to target , and distroy sweeper , use haste spell to support ur loons , as there are no air defence
( despite of one wizz and one arch tower , which would not be a cause of concern ) , u can easily distroy the sweeper !.. Then use ur draggs and loons on both the sides of other ad's and use ur rage spell accordingly ....
Boom u got 3 star , yeah use ur arch to clear the corner buildings if needed !...
