Is this my belated christmas gift @kstreet? In all seriousness, I want to know what your exact thoughts on black rhino is? Because yes, the big armadillo got it going right now, but the rhino has more utility. Also, running King Kong feels good, amen to no confusion.
Glad you got something from it! I can't imagine a scenario where you would take the twin strike option, so it's basically a 5/8 frontline. It stacks up fairly well against the Labyrinth Guard (magic) because it can attack.
For decks topping out around 6 mana, you'd always pick Pangolin, but you might add 2x Black Rhinos if you were trying to make it to 8-9 mana. On the other hand, in those control decks, you want to run 2x The Hunt, which makes the 6 mana slot really crowded. So you might go 2x Black Rhino + 2x Hunt, but the Pangolin is so good at the moment that it's hard to justify taking him out.
