Age of Origins Guide presents Medicis Factory Run:

This event happens weekly during first phase of the strongest commander event. Do it! Even if you don’t get far you’ll get a lot of free items without spending anything!

Take all the zombies you can as they don’t die in between battles or need to be healed. Ideally you can max cannons and have a proportional front line just so your zombies can become the tanks and focus.

Buffs you want to prioritize zombie hp, zombie count, long range attack or you can focus on part boosts.

You can use buff items before or during the event. Even low placement will give you many energy jars for titan evolutions so don’t forget to do it!
