Snover (Japanese: ユキカブリ Yukikaburi) is a dual-type Grass/Ice Pokémon introduced in Generation IV. It evolves into Abomasnow starting at level 40.

What level does Abomasnow evolve?

Abomasnow evolves from Snover starting at level 40. It can Mega Evolve into Mega Abomasnow by using an Abomasite.

Is Snover good diamond?

Snover certainly isn't a bad option, but isn't a Pokemon that I'd personally use. Snover and its evolution Abomasnow certainly have their merits though, in particular their very early access to Wood Hammer, a great Grass-type nuke that will deal very heavy damage to anything doesn't resist it.
