I wonder what Suteguma's "abilities" are? He managed to beat the poker master consistently with only a slightly better hand each time. If he had some sort of way to peek at the opponent's hand, he shouldn't have been limited to 'barely winning' all the time, but instead always win whenever his hand was bigger. It seems he has some way of seeing the opponent's cards, but it's either 1) Limited, or 2) Not limited, but he barely won each hand on purpose to taunt his opponent?
I noticed it shows a camera on page 2, which reminds me of the Terrorist gamble where he used artifical vision to cheat. But even if Suteguma somehow had that, he shouldn't be able to make use of it in this Tower gamble, since it required rigged cameras. I'm thinking he has a more fundamental ability similar to Amako that could be used to cheat...
