Phan, here are the classes of special effect you can upgrade to:

Necromancer, where you can summon Knight Zombies and Wizard Zombies, too.

Manager, where you can summon All Star Zombies and Super Fun Imps, too

After selecting one of those, you may upgrade to Overlord and be able to summon Gargs.

By the way, your zombies are under your control.

Not updated, give me a few hours.
