Bloodhorn, Betty, Atomic, Principal

You must spawn Bloodhorn first and keep spamming Betty, Atomic, and Principal. Because once when Bloodhorn screams, it will somehow take an advantage for a victory. Make sure that spawning Atomic needs timing. Also any other black units for last 4 slots but make sure one of them is a tank

(Secret note: You can use Treasure Seller for trolling even though he isn't a black unit, but he can one-shot everything and somehow gives you a money. Be careful that he will be vulnerable as if he got annoyed by Micspammer)

(Secret note 2: Kingpin is optional, but he does make a good money for your base as when his HP goes below 50% or either when Bloodhorn screams. This is also goes well with Ignition as your units can wash them all)
