>>41424185Greedent is legit pretty good. You could go with a physical tank set that annoys with super fang:
Greedent @ Ganlon Berry
Ability: Cheek Pouch
IVs: HP 252 / Def 252 / Spd 4
IVs: Spe 0
Stuff Cheeks
Body Press
Super Fang
Gyro Ball
While limited by this gen's toxic distro you'll be surprised by what kind of things this can tank. On a team with good toxic spikes support this kind of set would be a pain.
You could also go with a trick room sweeper set:
Greedent @ Sitrus Berry/Chople Berry
Ability: Gluttony/Cheek Pouch
Evs: HP 252/ Atk 4 / Def 252
Ivs: Spe 0
Belly Drum
Gyro Ball
Wild Tackle/Psychic Fangs/Earthquake
Superpower/Body Press/some other coverage
Sitrus Berry gives you enough hp to get a second shot at sweeping if forced out by a hazer or revenge killer, Chople Berry lets you tank mach punches hoping to cut your sweep short.
Just make sure you use its unique strong traits of top class physical bulk and cheek pouch supported sweeping and Greedent will surely find a niche.
