Yes.

Craft is actually a number of separate skills. So if you have the class bonus for craft you have it for all the skills in the craft "family".

Does every specialization of Craft you take get the class skill bonus, or just the first?
Alice and Nicholas each control five Elvish Mystics. Each graveyard has a Canker Abomination and nothing else. Alice casts and resolves Exhume. 

How many Canker Abominations remain on the battlefield after state-based actions are checked?
