You might say this army is a "Healer-Giant with Wizards providing firepower" OR "Healer-Wizard with Giants as meatshield" Probably both make sense, and this seems confusing, but the complexity is what attracts me!

The enraged giants will crush every defenses in their path, while the wizards can devour the rest safely. The help each other out: Wizards have high DPS but low HP ; Giants have high HP but low DPS...

See? This is a Win-Win method in replace of the fragile Healer-wizard and the slow Healer-giant! TRY THIS OUT! You'll love it!
