Why would anyone play this card over Mage guild? Sure, it gives a little more wall for 2 less resources, but it doesn't have a change to draw rare mages... I think this card should either do more wall and tower or maybe raise mage tokens by 10 or something.
Also, I think it makes more sense to switch this card's title with Mage guild... For some reason I picture the tiny little cottage housing a mage, but not sure what kind (common or rare). Just a thought.
