Pro Scout:

Strange festive professional killstreak stock set. Why? Because they are strange, festive and badass in every possible way and scout is the only class that has so effective stock loadout that it's used in comp play too.

Seriously skilled spy:

Revolver/diamondback
YER
DR

As name says, needs skill to get behind enemy with the DR and get the first stab. Revolver in place of the ''casual'' ambassador due to this type of spy relying more on the YER and thus, if something goes wrong, there usually is no time to aim. Diamondback can be used too, but it takes an addittional bit of skill, as you need stabs to gain crits, which make this weapon the most effective.

This isn't a single class, but a serious troll. Even more serious than wombo combo or über med duo.

Medic and Spy, both on different teams:

Spy:

Pref. Diamondback, only used if med dies and you have gained stab crits.
Cloak and Dagger
YER

Medic:

Any
Stock or kritz
Pref. Übersaw


Fairly simple: Spy needs to get a single stab, then med starts pocketing him, making spy about 200% less obvious and as he has the YER, the medi-beam never stops. This usually leads to a kick vote against the medic, but so what? This is the top class in the art of trolling.

Drunken Fakir, AKA Lucksman:

Huntsman/Frotified compound
Jarate/Razorback
Shiv/Bushwacka

Frontier Justice
Pistol
Gunslinger

Build sentry - Get at least 1 kill - Destroy it - Build new - Use crits at some point - repeat.
