The Mass-Giant Healer attack strategy is mainly used for farming large amounts of loot within the Storages in a base. Now, just beacuse I say this is for farming, doesn't mean that it can't be used for pushing, but if you wanted to push to Master's League with this strategy, be sure to expect 0-2 Star attacks, this is because you will see higher Town Hall levels and more built bases up in the 2400 range. So, because of this, we will focus strictly on the Farming aspect of this attack. Be sure to bring 5, Level 6 Giants and a Poison Spell to this attack as well, level 5 giants will do as well.

Minimum Troop Housing Space Required: 200 Minimum Spell Housing Space Required: (not specified)
Drop the single Barbarian or Giant (whichever best) to lure all the Clan Castle troops from the enemies CC, drag it out to a Corner with your archer and use your poision spell or some wizards to take out all of the CC units.
Start your attack on the side where an Air Defense can be reached best, if Air Defenses are Symmetrical within a base, attack from the side with the most point defenses. Drop the rest of your giants in a spread fasion and not all in 1 group w/ your CC Giants.
Drop the preffered amount of Wallbreakers it takes to get into the base, avoid Splash Defenses (Mortars & Wizard Towers) while dropping these WB's.
Once your Giants start undercoming alot of fire, be sure to drop the heal spell in the predicted way that Giants are going (Hopefully towards an Air Defense).
When the Heal Spell expires or when an Air Defense falls, drop both healers to give backup to the giants, then spread your wizards to funnel your Barbarian King into the base.
Drop the Rage Spells in the direction the Giants and Healers are going, you may also Rage the Wizards and King if they are having trouble cracking the base. (Tip: Drop a Rage if you predict the Healers will be targeted by an Air Defense)
(No execution notes)
Sit back and watch the loot real in. You could get away with Cracking Mid-Tier TH8 Bases. I hope this guide helped, and don't forget to like the page and Clash on! :)
