Sorin Markov for Garruk, Primal hunter
Fair trade or not?
If not who is getting the better deal?
Dose it really matter as long as your getting what you need? (not much value difference in the cards)
In terms of money, a zendikar sorin would be worth an m13 garruk. But seriously...if one person needs a sorin and one needs a garruk, a couple bucks don't matter really :p seems fair to me.
