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.
