Ferrothorn @ Leftovers
Ability: Iron Barbs
EVs: 252 HP/ 4 Def/ 252 SDef/ 0 Spd IV
Leech Seed/ Protect/ Bulldoze/ Spikes/ Stealth Rock
Ferrothorn has amazing bulk and decent attack, so I made a set to work with those stats. Curse is the crux of the set boosting the thorn's massive defense and decent attack, and the speed drop helps Gyro Ball's power. The EVs maximize special bulk as Curse improves both physical stats. Power Whip and Gyro Ball are for STAB with high power but somewhat poor coverage. The last move is a puzzler. Bulldoze can help with Steel Types and might OHKO a fire type with prediction. Stealth Rock and Spikes are considerable, but remember that Ferrothorn is busy with setting up. Leech Seed is helpful with healing, but again Ferrothorn should be concerned with setting up. Protect can scout for threats and stall for a healing turn.
I am a roleplayer. I have fun hanging out in the RP section of the forums. If you have a problem with that then I invite you to dance forever.
