Yeah, there are some fast 'mons who can learn **Trick Room** (though it is useless).

For base speed > 100,

**Pokémon (Base Speed)**

- Galarian Mr. Mime (100)
- Celebi (100)
- Jirachi (100)
- Palkia (100)
- Victini (100)
- Comfey (100)
- Nihilego (103)
- Meowstic (104)
- Galarian Rapidash (105)
- Gengar (110)
- Swoobat (114)
- Starmie (115)
- Espeon (115)
- Azelf (115)
- Alakazam (120)
- Calyrex Shadow Rider (150)

These are the Fast Pokémons who can learn Trick Room, Calyrex Shadow Rider is obviously the Fastest.

If you want to include Mega Evolutions,

- Mega Gardevoir (100)
- Mega Gallede (100)
- Mega Diancie (110)
- Mega Gengar (130)
- Mega Alakazam (150)

Here, Mega Alakazam ties with Calyrex - Shadow being the fastest Trick Room user.

Source - learnt by TM (Those who can learn by level up don't have good Speed)

There are also some fast mons who can learn **Speed Swap**.

- Victini (100)
- Emolga (103)
- Galvantula (108)
- Raichu (110)
- Swoobat (114)
- Alakazam (120)
- Ribombee (124)
- Calyrex - Shadow (150)
- Mega Alakazam (150)
- Pheromosa (151)

Pheromosa obviously the Fastest.

**'Mons who can learn both of these are:**

*- Victini (100)*

- Swoobat (114)

- Alakazam (120)

- Mega Alakazam (150)

- Calyrex - Shadow (150)

Clearly, *Mega Alakazam* ties with *Calyrex - Shadow* being the fastest Trick Room and Speed Swap user.

Also refer Moveset Searcher and type these moves for clearer understanding.

Hope this helps :)
