(This step is only necessary if the enemy is part of a clan.) First, use 3-6 archers to lure the troops out, and poison them with both spells. Keep the enemy troops in the spells with the archers. If the CC is too deep to lure, you may want to just move on to another base.
Next find the flattest side of the base. Drop your giants there. Quickly use a couple wallbreakers to give them an opening. It is safest to drop the breakers close BESIDE where the giants are attempting to break through. This will make sure mortars and wiz towers which are shooting your giants won't kill your wall breakers. At this point, you may also want to drop a heal spell on your giants, with the majority of the spell in the area your giants are going to.
Use 4-6 wizards to clear any buildings on that side of the base, keeping them close enough to the giants that defenses will focus on giants, but far enough that they will clear all the unimportant buildings close to the core penetrating area your giants are creating.
Once your wizards have cleared any distracting buildings, drop your pekkas in front of your entry gap in the walls. Make sure you place them so that they will go into the base, not go around the edge.
Hopefully, your giants will be in the thick of fire now, with the pekkas incoming. Send some more wizards after your pekkas, and drop another heal spell on your giants if they are taking fire from a wizard tower. If the air defenses are down, go ahead and drop your healer too. sometimes you may need to drop it earlier, when your giants are first entering the base.
If you have not used all of your wizards, archers, and wallbreakers, use them and your Barbarian King on the side of the base opposite your original entry. This will distract some of the archer towers and canons, along with bringing some more firepower more quickly than sending through the maze of walls again.
Now celebrate your victory! As a side note, it is always better for you to adapt the strategy to fit you. This strategy is a variant of the GiWiPe, which is a variant of the GoWiPe. It may not fit how you play, so tinker around with the troops, and mold it to fit your style. Happy clashing!
