It's a petty thing, but I just can't entertain any arguments from someone that spells the letter "M" "Mee".

More broadly, the conning ability of carnymancers combined with the low loyalty of freshly turned units means that any carnymancer you hire is probably conning you/your side, first and foremost. If there was a regular business in hiring independent carnymancers, then there'd be little incentive to protect your side as an investment. All they want from you is your schmuckers and then they can move on to the next gig when their help proves too little to save your desperate side. Or however else they'll spin it to put all the blame on their previous employer.
