Midori is uneligible to play W5 because he was previously in Latin Kart in his MKU history
Rule 1.2.d applies :
1.2.d. Players are allowed to play for the team they are registered with and that team only.
i. If a player is caught playing for a team they are not officially registered for, the team will have that player’s score subtracted or receive a default penalty of -120 (-100 for 5v5) for the respective match at staff's discretion.
I'm deciding to just withdraw points from Midori (57), so ML will be receiving a 57 points penalty for this match
Final score : ML 383 - 544 NRB
