I love how the new champ is presented
*He gives people absolution from their problems. We definitely know that he physically removes them from their problems, but does he also exert some magical power to make it seem as though the problem never existed? He's been all over the world, he knows the best places to take people in order to fix their problems.
*He feeds on the hopes/dreams of people. He can't get into the "dining hall" of the heart because he hasn't given those people hope/a dream yet. The people let him into the dining hall of their heart by letting Tamm help them out.
*HE'S A CATFISH. Deception at it's finest. "The price is minuscule". Yes, it's a small thing to let him into the dining halls of your heart, you just have to open the doors to let him in. Then he crushes your hopes and dreams later on. Isn't the best part of life being able to live out your dreams? A seemingly small price takes the greatest toll possible.
*Waiting years to cash in on his deal? He let's his food "ferment", waiting so long to the point where his victim's suspicions are long past, life is great, nothing can go wrong, then BAM. Oh so savory
Theory incoming, imagine if the Handsome Gambler was Twisted Fate? His luck ran out early in life, came across Tamm, was delivered to a kingdom, had his wife-to-be killed by Tamm, then goes to Bilgewater to track down Tamm while doing his gambling shenanigans, gets tied up in Zaun to learn magic so he can bring back his wife-to-be, gets caught up with Malcolm Graves, turns Graves in to the authorities, gets his experiment, and now has his magical powers (albeit, not resurrection powers).
