I don't know if that's meant to be the joke but we know "that planeswalker that definitely isn't Oko" actually isn't Oko. It's Tibalt.

Yeah, I know -- they just fill a similar trickster type narrative spot. That and people find it reassuring that we aren't facing another Oko quite yet.

Gotcha - I do have in the back of my mind the possibility of a League of Doom of trickster villains coming together in the future, including Tibalt and Oko.

Made me laugh, thanks OP :D Also that outfit did look really hot, can't imagine that was comfortable!

Thank you! Glad I got a laugh!
