Totally agree with Sp12er. I don't think using the "It's just a fan-made concept servant" card makes it okay to create a really OP, game-breaking servant. Just because Merlin broke the game once doesn't mean it's ok to do it again.

Also, don't be discouraged, I'm not saying you should stop making these concept servants, I'm just saying that I think you should also think about balancing, not only according to the gameplay standard but also lore-wise.
