I put GCoJ every so slightly above Tibalt because CoJ can tick up to doing something potentially useful in an EDH game using an ability that does nothing rather than using an ability that's a horrible version of Gamble. It's pretty close, though. But "Do nothing" > "Most likely makes my situation worse" for + abilities.
I could see it if Champion of Justice was 2 mana. I'm okay with burning 2 mana on a joke card that maybe ends up reading "prevent the next damage target unblocked creature would deal to you" if I'm lucky, but paying Gideon, Ally of Vehicles mana cost for CoJ? Not happening.
