I have to agree with the guy who suggested Helm of Obediance Combo. Anyways, are half of the things that people have suggested here (Solidarity, Quinn, Enchantress) really able to be considered "Competitive" these days? What major events have any of those put a substantial showing in recently (i.e. top-16'ed)? I can't recall any such events where any of those have top-16'ed. Sure, they have some cute interactions, and can be quite potent if they can get their win conditions on the field. But they are also slow and easy to disrupt for the most part. I would have figured they are more or less obsolete.
