I finally managed to get my hands on a foil borderless Terra, Magical Adept, and I'm going to go all-in trying to break her.
I've been seeing talk about her being a Food Chain commander, but I'm too stupid to see the line, since she doesn't reduce her cost, or gain more fodder like a Prossh

I'm guessing it's a case of hard mulligan to hit the Squee/FC, and the means to search out the other part, then you just spend all the mana self-milling yourself with her ETB to hit the breach line?
