Iron Head
Stone Edge
Thunderbolt
Avalanche
Just a few more suggestions for you.
I would stay away from the magnet, NMI, and those other ones if you want to use avalanche the right way. Focus Sash is pretty good.
Stone Edge: Keep it, it seems to be fine in the moveset.
Iron Head: Maybe you could switch it if you want.
Thunderbolt: It's good for against water types, the only remaining weakness you can actually cover.
Avalanche: This should take care of any pesky ground types that come after you, along with any other pokemon weak to ice type attacks.

That moveset really doesn't seem all that good to me...
The Nevermeltice only increases Avalanches power, nothing else.
Metal Burst will only do damage if Bastiodon is hit, so that leaves a big weakening if the opponent uses an attack like swords dance, or any other Attack/S. Attack raising move, it's worthless.
Block isn't a good choice unless you want to keep an opponent from switching pokemon. Stealth Rock once again, won't deal a high amount of damage unless your enemy switches. And Thunderbolt is okay.
Avalanche is still okay.
Toxic? It's not really all that good unless you have use it the right way. Using it with block is decent too.
