I think there shouldn't be achievements that can be "cheated." For example, two players can make a pact to exchange all of their creatures just to get that achievement and then to exchange them back. And that sort of things. I just think it's lame.
Also, I'd like to propose the idea that all achievement can't be reached. (This applies only to hard ones that actually need to be worked for.) That way people will have to choose witch ones they actually want to achieve instead of just wanting them all no matter what. That way every one would have unique sets of achievements (sort of like choosing principles). This can be done by having certain achievements exclude each other.
Some ideas for achievements:
