How to 3 stars this base

L1 hounds will rip that base to shreds, as the enemy strangely (stupidly) put all his ADs on the outside.

Penta, without question. 4 hounds, L3 hound in CC (or any hound in CC), 18 loons, 1 hog, 5 archer. Haste in CC, 4 rage, & a poison

Pull the CC, poison it (I'm presuming the CC can be pulled with single hog--can't see range of it though to confirm). It's likely a dragon. Anchor with archer to pull the dragon (as whatever else should have died to the poison) to the hut at 9:00. Drop a few more archers and AQ when the dragon gets close. You will barely even need to cloak your AQ, as the dragon will be close to dead from the poison, but cloak her if needed.

Then start penta. Drop 2 hounds on one of the ADs at ~10:00 and 2 hounds on the other. Drop a total of, say, 10 loons, 2 per defense, on all outside defenses. Rage the loons into the ADs.

Then, drop your CC hound on the AD at 5:30 & 2 loon on each on the AT and cannon at 6:00. Rage loons in. Then, once that AD goes down, drop your last 4 loons, 2 per defense on teh AT at 4:00 and the AT at 3:00. Rage loons in.

B King will likely be used for cleanup

Shortly after you drop your first 2 rages, always be on the lookout to drop your haste, which will likely be somewhere in the middle of the base.

You should blow torch this base with considerable ease. I'm actually worried that 5 hounds might be too much and you should drop one for 6 more loons...

EDIT: I just realized, after I typed all this out, you don't even have L6 loons and, instead, have L4 dragons. Holy ♥♥♥♥...that is about the most worthless upgrade to be selected at TH9; the best usage is for CC donations... All that I said above is now highly suspect, as L5 loons stink at TH9.
