Steel types all the way! They hit hard and they play hard. My gym would be a series of small platforms which you have to link together to form a path to me, with multiple dead ends and a bit of backtracking required.
Since gym leaders never get to have more than 5 'mons, I'd have
Lvl 48 Lucario- To give challenges a curveball. I mean, who expects a STEEL type to be fast, frail and hard-hitting?
Lvl 48 Ferrothorn- It can use Leech Seed, Ingrain and its high defense to thoroughly annoy anyone who goes against it.
Lvl 50 Bronzong- I'd have it with Heatproof and Magnet Rise to get rid of my two most notable weaknesses, and Trick Room and Extrasesnory to sweep whole teams.
Lvl 51 Skarmory- Every Steel type specialist has one of these, its almost a law.
Lvl 53 Aggron- Not only is it a tank, but it can mega-evolve to make it even more powerful. By this point most challengers will just throw away their 3DS in frustration.
I'd include pictures, but I don't know how to copy-paste them onto a post or how to use a spoiler tag.
Sorry
