I don't pretend to be an expert on modern Magic, but I think it's about as balanced as a duel between two 3.5e dragons min/maxed with all the game's best options. In other words, it's rocket tag.It's been so many years since I stopped playing Magic the Gathering, so I don't know how balanced the current "edition" is.

...Assuming that both players can afford the good cards. If one can't, he's at a huge disadvantage.
