This is actually quite humorous. You see, Mega Torkoal has been done for
a hell of a long time now. I didn't have to win it, though to answer your question Sabre, it was deemed balanced. But for some reason, it has continuously been forgotten to be put on
every one of our completed Megas lists. It's still not on the current one. The person who made the slates actually thought that it hadn't been done and so it was put on the list. If you guys want to see, here's what it is:
Mega Torkoal (Torkoalite)
Fire ----> Fire/Steel (think of a furnace)
White Smoke/Shell Armor ----> Sturdy
70/85/140/85/70/20 ----> 70/95/160/95/130/20
New Moves: Flash Cannon, Flare Blitz
Concept: Torkoal is the only Fire-type with Rapid Spin and one of the only defensive Fire-types. So I got rid of its SR weakness and TSpikes vulnerability (Toxic immunity by itself is pretty good for a wall), which also grants STAB to Gyro Ball, gave it a much needed Sp. Def buff, and divided what was left into its Attacks and Defense.
