Low is a little mean for Skarmory, I feel. Fly is a pretty good move, Steel typing is great for random battles, and Skarmory does well against Marshal, Grimsley, some of Shauntal and a bit of Iris. Its movepool isn't bad enough to warrant a minus in my opinion. I feel that Steel Wing could be an option if you don't want to spend the shards for Iron Head. Personally, I think Roar kind of sucks in-game, but that could be just my personal taste.
My personal opinion is that Lower-Middle suits Skarmory better ([1/3]). Anyway, theorymon time!
Dewgong - Lower-Middle Tier
Availability - Mid-Late (Seaside Cave)
Notable moves - Surf, Aqua Tail, Blizzard, Ice Beam, Hail, Signal Beam, Drill Run, Dive, Toxic
Stats - Good HP and Sp. Def, decent Def, average attacking stats and Speed
+Available all year round and easy to catch - the most convenient Ice-type before Drayden
+Evolves immediately after capture
+Can easily Toxic-stall with Dive
-Stats are all too average for it to really sparkle in a certain role
-Doesn't shine in major battles after Drayden
100% of information in signatures on this forum involving percentages is false. If you feel as cheated by this atrocity as I do, don't you dare copy this into your signature.
Hold on... if this percentage was correct at the time of print, that means the actual percentage of false information is less than 100% if this signature is included. Which means that... no! I've become a slave to the system!!
