The Scenario
Greater Sci-Fi combatant
muh patterns
Fossil pokemon tend to be released in offense/defense oriented pairs. One is usually a physical attacker, while the other has better defenses and maybe some sp. atk. Tyrunt looks to be the attacker of this pair. Then the Rock type itself is also known for pretty slow defensive pokes, and a lot of Ice types are pretty bulky and slow as well.
Now, Amaura could be a special attacker based on its use of Aurora Beam, but if it is that severely hinders Refrigerate as most of the good Normal moves are physical. In that case I hope we get some new special Normal moves, otherwise the best it could get is Hyper Beam.
The absolute best case scenario for Amaura would be a fast physical attacker, and and if it got Extremespeed I would use nothing else until the end of forever. As it stands though, I don't think it will happen. I hope I'm wrong, but I'm expecting it to be a primarily defensive mon with above average special attack, that nonetheless learns some physical normal moves it will have trouble making use of due to low attack.
I want to like it, but I'm afraid of how easily it could be messed up.
