I have been messing around with this set for a while and I'm happy with the results. Here's the exact details on Mixed LO Garbodor. (actually had a workshop with it a week ago or two)
THEY TOLD ME (Garbodor) (M) @ Life Orb
Ability: Aftermath
Shiny: Yes
EVs: 4 Atk / 252 SpA / 252 Spe
Rash Nature
- Gunk Shot
- Focus Blast
- Toxic Spikes
- Giga Drain/Psychic
Garbodor becomes an amazing lure that's able to decimate pokemon like DD Rhydon, Steelix, and deal heavy damage to Gastrodon and other switch-ins. In addition, it's still able to maintain the 2ko vs Defensive M-Dino, 2ko Hariyama with Gunk Shot, etc. Psychic might sound silly but it lets you 2KO Garbodor, Vileplume, and Weezing, if your team ever needs it.
This of course isn't exactly perfect, you lose out on the opportunity to get a fantastic defensive spiker, but still.
(unfortunately Garbo can't ohko tank don, but it can definitely bopped a weakened one)
