My Ferrothorn right now has: Toxic Gyro Ball Power Whip Grass Knot
People say that it's best to replace Grass Knot with Leech Seed. I looked it up and serebii says it's an egg move. Does that mean my Lv. 55 Ferrothorn is a waste? If it's a male, then how am I supposed to breed for leech seed??? If I can't, are there any other life draining moves I can teach him instead of Leech Seed??
Basically, you're going to want to get a male pokemon of any of those species up there. Breed it with a female Ferrothorn/Ferroseed and you'll get an egg with a Ferrothorn that knows Leech Seed. If you don't want to go through with that, you can probably find an alternative move.
Alternative moves can be found at http://www.serebii.net/pokedex-bw/598.shtml
Now you're the only one here/ who can tell me if it's true/ That you love me/ and I love me.
