Poor old Jorah. You've just got to feel sorry for him in every single thing that he does. Yes, he had some shady dealings in the past, but since then he's been nothing but Daenerys' most loyal subject. At least until Daario came onto the scene and took things further with the Mother Of Dragons than Jorah ever could. Method Of Elimination: He'd relish the opportunity to reclaim his honour, but he'd also relish the opportunity to take Daario out Daenerys' life. Regardless of who he ended up killing though, Jorah's a dead man anyway due to greyscale. He'd no doubt survive long enough to seek some vengeance before succumbing to his condition and bowing out gracefully.
5. Tywin 'The Lion' Lannister
Tywin Lannister is the ultimate 'boss'. He just knows how to deal with every situation, and would probably be comfortable perching himself in a corner for the entire game, glaring other fighters into wiping out the competition. He wouldn't need to lift a finger. Method Of Elimination: In Tywin Lannister's eyes, he only ever had one blotch on his record and that was his 'monstrous' son, Tyrion. The dwarf was his weakness all along and would no doubt pop up with a lethal crossbow shot to end it all.
