I'm theory creating a deck and need to make sure this is sorted out.

Let's say I have [[Sauron, dino devotee]] out, equipped with [[stoneforge masterwork]], with [[unnatural growth]] and two other creatures out, one already has a saurian counter. I go to combat, UG doubles Sauron. Sauron attacks, putting a counter on my 2nd creature( and making them a dino).

What is his new stat line with base 4/4 & UG2x & SM+2/+2?
