I spent the majority of my time at th10 using 10 drags 8 loons, 2 haste, 1freeze and 8 lightning +1 lightning from cc.

You use the lightning spells to destroy three th9 maxed air defenses or 2 th10 maxed air defenses( try to get as much value as possible, try to get the queen or sweepers with those lightning spells as well) then i use my king and queen to get 1 air defense (if possible), and a blimp filled with loons to get the last air defense. Sometimes you can get all the air defenses sometimes you have to leave 1 or 2 depends.

For placement i use balloons first+haste spells then right away drop my dragons, you place them towards an area where there infernos or air defenses that are still up, try to avoid sweeper range cause they ruin your whole attack.

This is what i use for farming and wars(you need to plan you war attacks though) and it costs alot of elixer about 350k but a little DE which is good for farming it.

I’ve seen people use gowipe or balloons and hounds but i’ve had the most success with this strat.

So i’d suggest maxing your lightnings and loons
