Instead of Stun and Slam, I think Facetiox should have taunt and a damage barrier ability. Also, he should not be trained in Arcane, just mind. The reason for this is since Facetiox should think he knows it all, but actually doesn't. He should have cantrip, to represent how annoying he is in continuing to come back over and over again. Instead of elusive, he should have pest, for obvious reasons. Also, it might be a good idea for him to be a familiar that prepares a spell from your opponent's spellbook each round, so you don't know what it is until after the planning phase. Maybe his mana cost should be decreased to 4, and he should have the upkeep +9 trait (since he's high maintenance and a cheapskate) His stats should be reduced. Maybe no armor and 1 health (he's a lot less tough than he likes to pretend he is), and a defense of 6 that can only be used once in a round if he prepares a spell, twice in a round if he does not (he can avoid attacks by stealing your treasured belongings and putting them in the line of fire, making you hesitate to attack. If he doesn't steal from you, he will say something really nasty to throw off your concentration.)
I think the Facetiox you came up with on the other hand, actually sounds like a great card if you just take out the elusive and raise the effect die rolls a bit, perhaps adjusting the mana cost too. It seems like you're just trying to have a go at controlling playstyles and the players who use them, which really isn't nice.
Just saying!
