1st Class
Primary: DSR 50(FMJ, LASER SIGHT)
Secondary: R870 MCS
Perk 1: Lightweight
Perk 2: Fast Hands
Perk 3: Dexterity
Lethal Equipment: NONE
Tactical Equipment: Shock Charge(x2)

This class is a good one because on BO2 we can make tons of different types of trickshots with a shotgun, example: NAC SWAP, TITTY NAC, BASIC INSTA SWAP, ZOOM LOAD, etc.

2nd Class
Primary: DSR 50(LASER SIGHT)
Secondary: BALLISTIC KNIFE
Perk 1: Lightweight
Perk 2: Fast Hands
Perk 3: Dexterity
Lethal Equipment: Combat Axe (x2)
Tactical Equipment: Shock Charge(x1)

This class is a good one because is possible to make tomahawk trickshots which I highly recommend the use of the ballistic knife since its a secondary weapon and is... I would say the same category of the combat axe.

3rd Class
Primary: DSR 50(LASER SIGHT)
Secondary: Any SMG of ur choice(w/ Select Fire)
Perk 1: Lightweight
Perk 2: Fast Hands
Perk 3: Dexterity
Lethal Equipment: NONE
Tactical Equipment: Concussion(x2)

This class is a good one because I think that the use of the select fire on a trickshot make it rly clean even tho sometimes it would not show in the killcam. The use of the concussions make select fire trickshots even more cleaner(in my opinion). Of course u can use shock charges if u want ;)
