Please remember Rule 3.5.d.:
d. Players must use a Mii name which makes them easily recognizable as their alias on the MKCentral registry. Failure to do so will result in a -10 (-7 in a 5v5) points penalty for the match.
The Unknowns will receive a -10pt-penalty due to miaghost using a name that wasn't easily recognizable.
Final score is:
The Unknowns 557 - 417 Pirate Hackers
