Well, that was fun: just beat Garruk in The #XboxOne version of Magic 2015. Garruk is a rather drawn out battle, as he is actually two duels back to back; if you lose the second duel, you have to re-fight the first. And his second deck is filled with a lot of cheap, sanity destroying nuisances.
Took me three tries to beat him. Fortunately, on my third attempt, I was able to get an angel out with flying, which appears to be one of Garruks weaknesses.
Now, on to grinding out the card collection wins.
