how would you attack a base like that?

Use 3-4 hogs on AD without WT.
Maybe 5-6 hogs on AD with WT next to it.

Then, either mass dragon with a straight line from one side.
Or, loon all the outer defenses, then send a few hogs to lure cc, pull to AQ side. Clear there and kill AQ as well.

Then hogs (faster) the remaining buildings, but keep some or spread out in case double GB.
Your L1 minions can use to clear also.

I'd probably take a combo based on loons.

rush the AD with loons, rage them near the WT. Then do precise strikes on the other air targeting defs, where you can- similar to a holo attack. You'll then be free to clear up.

I should say if the loon attack hasn't pulled the cc, then pull it before you clear up. I'd probably take a couple of wizzies to kill the cc, just in case there is something in there you can't kill with a loon drop.

I've seen bases like this before where the air traps are centralised to ruin the raid at the end. I'd keep a few loons back to clear a path to the centre.

Final piece of advice, be quick. 3m will go faster than you think if you do it this way.

Gowipe is a good option

Hi

Use Gowi(wi/Pe) option.

Have a large clean of two side of the square with 1 Golem and Wizard behind.

The third golem, drop it in the corner between the two big side clean (when the clean is done).

Drop Heros and Wizard/Witch/pekka (behind third golem), they have to go strait to the center
(no more disturbating building around). It work but need to be skilled.

All the best bro.

To save elixir. Just use giants and wizard. Simple

This base is super easy to 3 star
