Ok here's the spacific answer: You get surskit at route 102,114 and 120
Route 120 is easier to get surskit. one time i found surskit at 102 2 times at the row. I really caught it.
OK level surskit up at level 24.Then it evolves to masquerain. that's how you get masquerain and obviously masquerain has intimadate ability.
You thought it's level 22? Well its wrong. It learn gust soon at level 27 i think. but im positive that it will learn that move at 20 somthing.
Surskit is going to evolve from about lvl 22, its evolution form is Masquerain.
Heatran is a ledgendary in Pokemon platinum.
There is not a route 233 on Pokemon platinum.
The routes in Pokemon Platinum begin in the 200s.
There's no Route 505 in Pokemon Platinum.
Go surfing on Route 299 and you can find a Masquerain. There is only a 5% chance you will find one.
Masquerain is a Bug and Flying type pokemon.

in Pokemon diamond pearl and platinum you evolve surskit at level 22 but in platinum you surf on route 229 ( desert route) 5% chance of finding it in the hoenn reigion route 114 as a suskit in diamond and pearl it is lvl 2 or 3 at lake verity as a swarm Pokemon
its evolved form, masquerain
the Pokemon unobtainable are surskit, masquerain, zangoose, lunatone and Roselia
You can catch masquerain by going to route 229. walk up the path north-east that's full of grass (you'll need a max repel if you don't wanna battle) and you should come to a really really small lake. surf on it (don't fish) and you should find a surskit. catch it and level it up once (it normally evolves at 22) and you have a masquerain. =] hope it helped!
Butterfree, Absol, Flygon, Masquerain and Roserade/Roselia
