Hey Referee, you're calling out this shithead's use of an illegal or rule breaking magic. You can go ahead and disqualify him immediately.
No-one said the referee is actually capable of stopping the asstard's magic...
And yes.. Shitty Noble Brother 101 may just have forfeited te match, but if our MC doesn't survive, or at least becomes severely incapacitated he'll still have fulfilled his primary job: demean lil' princess, deprive her of her knight, and make the redheaded bitch princess happy..
Things like "cheating" is minor compared to Getting Results and the continued patronage and protection of a political heavyweight.
Peeps will "forget" the cheating, they
will not forget the utter ruthlessness displayed, and ....reconsider their options for support..
These are people that do not play by our modern "fairness" ruleset...
