I am currently a maxed th6 in the crystal I league and it takes forever for me to gain trophies, this is understandable because of how long it takes to find an exposed town hall.

However sometimes I tap on the field on accident and lose battles, is there a way to ensure I get 50% on these high bases with only 150 barchers?

Also sometimes mortar + teslas overwhelm my troops, is there a way to still win a exposed base? I remember I once dropped two lvl 4 lightning spells on a lvl 5? mortar and it survived the attack, making me lose the raid.
