This little fella is no push over as it stands as one of the most powerful Bug/Steel-type Pokemon. With its snail-like speed, it screams for Trick Room and any Pokemon that are weak to bug and steel will instantly faint (even the bulky Cresselia) to it. This is quite a straight forward build for Trick Room so this won't take long. 

Strength
The best thing about this Pokemon is its Overcoat ability, since Overcoat got a nice buff in Gen 6, the ability allows it to easily face those pesky Spore/Sleep Powder users, as well as Rage Powder. However, it's too bad that prior to Gen 6, it's quite difficult to obtain the hidden ability because it's non-existent in the Pokemon Safari and ORAS. So the only way to get it is to transfer via Pokebank from Dreamworld (Gen 5). 

Tough luck to those who doesn't have Black & White 2, the next best ability is probably Shell Armor that resists critical hits which seem to be quite common these days. 

Besides that, it has amazing Attack and defensive stats overall. Its full EV pump Attack stat can OHKO a bulky Cresselia aforementioned, even those who are neutral against it are gonna get hit like a truck.  

Weakness
Aside from the obvious slow speed movement, it has a serious 4x weakness to Fire and Fire-type moves are super common in the metagame, so with that, you will need a good Water/Rock/Ground-type partner that deals with it.

Another way to counter this is using a Pokemon that has Flash Fire ability, you can always make a surprise switch and get a nice Fire boost. This also works for opponents who wants to use Will-O-Wisp on your bug knight, but watch out for Pokemon with Intimidate ability. 

Moveset

Although the bug knight is ridiculously strong, it lacks a wide variety of moves which makes it predictable. The two main STAB moves are Mega Horn and Iron Head by default, Protect is also needed to fend off incoming Will-O-Wisp or Fire-type moves. 

For the third attacking move slot, you can either go for Drill Run or Knock Off. Drill Run can counter Fire-type Pokemon nicely, but it is an egg move from another Pokemon that can only be obtained in Black and White Move Tutor. 

Knock Off is also a good option with the recent buff, with its already high Attack stat, it is likely to OHKO anything that moves, if not, at least it will “Knock Off” the item away. 

If you're thinking of Quick Guard, I guess you can consider it to stop those who has Prankster ability or those with priority moves, but it’s better off destroying when in Trick Room.

Closing thoughts

Had a blast using Escavalier, but it's unfortunate that I don't have any way of getting Overcoat ability or else it would have been one of my most important Trick Room members. Oh well...you can't have everything sometimes.

So Escavalier, I choose you! Glhf
