"I meant you haven’t met the planeswalker card yet not the character. You may have already met the character." By that logic, you could have been talking about Bolas.

It's an Amphin Ooze.
I'd love to hear a point/counterpoint on targeting restrictions (like how Oblivion Ring-like effects printed lately can only hit your opponents' permanents).
That has potential. I think Sam and I might disagree on this one.
Monstrosity is my favourite Theros block mechanic - Where is it on the Storm Scale?
