Wizards of the Coast reserves the right to disallow any team name it deems offensive and/or obscene. Tournament officials may disallow teams from registering team names that may be considered offensive and/or obscene.
It is important to remember that Wizards of the Coast is the ultimate arbiter in what may be deemed offensive. While certain names (come on, you know what they are) are directly offensive, others may also be deemed unacceptable. Do not be surprised if a name that subtly insults players or officials is not allowed. Similarly a name that touts another game or competitor may also be viewed as poor.
