You can look through the thread because there's no point repeating the old Geist/Clique arguments. lol Point is, Geist is a great card. It just doesn't further our main game plan. Clique does.

Canonist might have a slight advantage over Meddling Mage when it comes to Storm, however I'd still argue for Meddling Mage's versatility. After Cliquing a Storm player, you get to see what is in their hand and what could be threatening. If they are holding a tutor, it's probably best to name the tutor so they don't have the option to search for their combo piece or their bounce. Against Canonist, they can search for the bounce and go off next turn (or maybe even that turn).

In addition, Mage is useful against Dredge. Canonist is definitely better than Mage against Elves though being able to Snap back removal is pretty relevant there also.
