[@vancexentan][@MeteorD][@Cu Chulainn] Honestly I don't see a problem with it. Yes he hard-counters Kuro no Archah, but that much was made explicit in the sheet, and speaking as the GM here, I'm sure the team of low-key psychopaths and elite magi will find ways for their Servants to cope. Every Servant on the enemy team can't have an [i]overwhelming[/i] advantage against ours anyway (only [i]most[/i] of them >:D) because it'd be boring. 

Besides, this way we get to troll Mordred even harder, and by that I mean compound her PTSD flashbacks to the Battle of Camlann. Lancer is accepted, but I'm holding you to the limitations you've placed on Rhongobongo 2: Electric Boogaloo from both a character-focused and mechanics perspective.
