Hey, I saw your RMT and noticed that you were using a... Modest Scarf Magnezone.
:evan:
Scarf Magnezone might seem like a revenge killer, but in reality it fails to outspeed anything noteworthy even with a Timid nature, losing to Adamant +1 Dragonite and Gyarados and failing to outspeed max Speed Starmie (all of which can OHKO Magnezone). It's honestly a terrible revenge killer. You'd be much better off using a Timid Scarf Magneton in my opinion, which retains Magnezone's ability to trap Steel-types while actually outspeeding things - the loss in power will be noticeable, but really it isn't as bad as it seems. (I wouldn't have bothered normally, but I wrote Magneton's OU analysis so...)
If you're dead set on keeping Magnezone, you might benefit from replacing Protect on Gliscor with Stealth Rock and giving Garchomp a Choice Scarf and Stone Edge, for a more reliable revenge killer. Regardless of these changes, changing Lilligant to a Timid Life Orb variant will allow you to outspeed +2 Modest Landorus in the Sun (if you use at least 236 Speed EVs) and OHKO with HP Ice, taking a major burden off your shoulders.
