Went 1-2 for the night.
First round was against some Mardu homebrew. Heavy fliers in the form of Master of the Feast, Butcher of the Horde, etc. Didn't get to see too much of the deck. I foolishly boarded in creature removal instead of swapping my Doomwake Giants for Arbor Colossus to take care of the fliers. A quick 0-2 loss.
Second round was more interesting. Ran against a pretty standard Temur deck. Won the first round with basically the perfect ramp into heavy hitters. Post-board he seemed to grab more counterspells and won, since I couldn't make my ramp quite as well. Third game went to time, with me keeping him at bay with some of Pharika, God of Affliction's snakes and eventually a Hornet Queen to manage his Ashcloud Phoenix. I maintained a favorable board poisition, even though my See the Unwritten only got an Eidolon of Blossoms and a Courser of Kruphix. Eventually I got a second queen in play and with Pharika active, kept whittling away his blockers until I could bum rush him before he could re-activate his Ashcloud Phoenix enough times to take me down.
Third round I should have just walked away from. I don't know if there's an archetype for this deck, but it's basically nothing but counterspells, creature removal, Dig Through Time/Jace's Ingenuity/Treasure Cruise, Perilous Vault, and a single Pearl Lake Ancient. Really, my only hope against this deck type is that he doesn't get enough land to hit me with two counterspells in a single turn. I boarded in Stain the Mind, Thoughtseize, and Reclamation Sage, along with my Arbor Colossus (since the giant's constellation isn't useful in a deck with no creatures). My only real hope against this deck is to get a Stain the Mind past his defenses and snatch up his Pearl Lake Ancient, or hope that I can pull enough creature removal to keep his ancient in his hand for a few turns. If I see this deck again, though, I'm probably just gonna walk away. It's no fun to play against decks like that.
