Barrin, Master Wizard

No, not the best card ever, but useful in some situations. Use it with a Phyrexian Infiltrator and you've got reusable creature destruction in blue/black. In a mono blue deck I use a similar tactic with Seasinger, Puffer Extract, and Phantasmal Terrain as needed.

Use this with Deranged hermit as the previous comments suggested, you simply sacrifice one of the squirrels that comes into play when Deranged hermit comes into play to return Deranged hermit to your hand to play him again to gain more squirrels, with this combo you can create an endless army of squirrels. there are good potential combos with this card but all around it is quite weak.

loved this dude and the artwork he rode in to town on. now, if i could just break him with some insane combo....maybe tribal with wizards or i've heard of using him with 'deranged hermit.' geez, i know if i just think long enough and hard enough it'll come to me.........
