Hybrid Golem Launcher

Start the attack with a Fireball placed nearby simply to create good funneling. Redirect the Warden with the Queen and then deploy all the spam right after.

Cut from the opposite corner with the King and a couple of Barbarians, letting the King handle the outer cleanup so your entire army moves into the core of the base.

Use Overgrowth in high-risk areas where you need to redirect the army, and deploy the Royal Champion with the Frost spell to slow down key defenses.

The rest of the spells are just normal management.
