The Leader (mcu) vs DeVoe (cw flash) vs Sister Sage (the boys)
These peeps have superpowered brains and manipulate events from the background to achieve their end goals.
Round 1: If each of them was a campaign manager for a particular candidate, whose candidate would win?
Round 2: If each of them were trying to kill the other two, who would win? They're not on a battlefield, they're just in civilization, and they can take as long as they like.
Round 3: If they each devised a game for all three of them to play, who if any would win two out of three games?
