Lubos Lauer, more than just a judge
Lubos had a Golgari deck, with a hint of white. His early creatures were Centaur Safeguard and Dimir House Guard, and the two players started to trade a little damage. At some point, Antoine sacrificed his Transluminant, as his plan was to use Cleansing Beam on Lubos' Safeguard. When he realized that his Legionnaire would die from that as well, he took it back, and instead just blocked with his newly acquired spirit token. It looked really bad for Antoine, but he topdecked a Rally the Righteous and could deal the last damage just before he died.
Game 2 was a lot less interesting, as Lubos was stuck on two mana, and Antoine's weenies just got to hit him unopposed.
Antoine won, 2-0
