Thought I would share my BO1 version that is a little unorthodox but so far has been great.
edit: I was gonne say you might not need that many lands, but since you dont run opt and have 4x Surge Mare, it's probably for the best you run 21
Yup sometimes I wonder if I should be running 22.
Been running 1-2 blink instead of exclusion. I figure it's 2 mana, instant speed and can bounce more than just creatures - bouncing a wilderness reclamation after they tapped out to cast it is satisfying - and if I get flooded (with 19 lands it happens with obsession going) can pay the kicker to draw a card.
Not sure if that outweighs having another creature to attack with, but it's a spell worth considering I think.
Nothing wrong with running blink but I prefer the extra bodies and like the tempo swing the mage brings vs aggressive decks. + He is a wizard that helps get the discount rate on
Wizard's retort.
My version is all about adding bodies to the board where the other versions are little more controlly but run pterry so there is a reward there.
