You definetly need to run a scarf with Krookodile.So I was considering putting Excadrill on my team but apparently he is now banned along with Thundurus is this right? Anyway I need a replacement. I was thinking Krookodile.
Krookodile @ Focus Sash
EVs: +252 Spd +252 Atk +4 HP
Night Slash/Foul Play
Dragon Tail/Outrage/Dragon Claw
I really just need a STAB Eq on my team and with Krook's Moxie I think one he kills something that it would be very good for me. But his frail defenses kind of make Focus Sash a must. He is also a good counter for ghost types which are very versatile and slightly scary. (Such as Gengar) But I don't feel he's the best replacement any other ideas?
Theres a thing called Landorus in the sand, try it outi don't thinks Scarf is really this necessary on Krookodile. he's speed's bigger than lots of pokémon, and he has a great attack that can be very useful when used correctly.
either way, i don't know why you chose Krookodile, i think Gliscor, Donphan, Gastrodon, Quagsire, Hippowdon and Whiscash are better options than him.
