Golett is often overlooked in LC, and aren't very common, but they can be so so good if you use them right! Here's the set that I use, that prove to be really good for backup support.
Titan (Golett) @ Choice Scarf
Ability: Iron Fist
Level: 5
Shiny: Yes
EVs: 164 Atk / 54 Def / 54 SpD / 236 Spe
Adamant Nature
- Shadow Punch
- Earthquake
- Drain Punch
- Ice Punch
I often find that, even with EV investment, Golett doesn't always outspeed. That's why Choice Scarf is a great help (mostly lol)! Shadow Punch and Earthquake for strong STAB moves, Shadow Punch never misses, and gets an Iron Fist boost. Drain Punch and Ice Punch both get Iron Fist boosts, and as well as them both having great coverage, Drain Punch heals too.
Hope this set helps!
