Does Epic Spell Wars actually contain profanity?
No, aside from the rulebook's preamble, it does not contain profanity.

Samples:


Sir Lootzor's // Polished // Snakedance
Ben Voodoo's // Boulder-iffic // Bedazzlement
Pam and Hecuba's // Two-faced // Cone of Acid
Midnight Merlin's // Devilicious // Power Vortex
Whirly Do's // Burst-o-Ramic // Meatier Swarm


At worst, it's just a couple of cards that can be removed.



The rulebook of the sequel (Rumble at Castle Tentakill) is clean, and the following are the only offending cards:


Bitch Witch
Sexsquatch
Dr Gravelovers (the art is iffy)
Auto-Erotic 
The F-U Suit (spelled exactly like this)
