Alternate name: Drinking Games
The Biersal will host a party, but you're forced to follow their rules.
"You will face a mass wave sent from the Biersal. Your towers will be under a spell and take turns drinking the non-unique potions dropped.
The Biersal will give each mass creep a potion to deliver."

Card use analysis:
I imagine this working where each tower will drink a potion as they're dropped (the default order seems to be build order). Once all towers have had a drink, then they start over and keep drinking potions dropped by the mass creeps.
I expect the mass creeps to be carrying white potions.
I don't expect this prophecy to be very strong. You get 20 white potions, but your carry would normally only get 1-3.
With Cthulhu, you'd get more like 7-10 potion splashes (5-7 effective potions).
With SnoreFox, you'd get more potions depending on how many rabbits you eat. Estimated at ~5.
