I went 3-1 that day. It was so scary to mulligan up to 5 every round, but i managed to show a good result! =)
Round 1: 2-1 Win. Azorius Control. That player was a newbie and came to Magic only since RTR block. First game deck played perfectly: despite turn 3 Detension Sphere on 2 my Champion of the Parish I made a lot of pressure on the board. Game 2 I had to mulligan up to 5 and drew only one land. 3rd game was awesome, a lot of 1-2 drops from me.
Round 2: 2-1 Win. Bant Hexproof. In the first game my opponent showed Fiendslayer Paladin turn three and 2xRancor and 1xUnflinching Courage on it turn 4. Second game my opponent was manascrewed and I managed to reveal approx. 5-6 creature with a lot of swing every turn. Game 3 we both mulliganed to 5, I started with only 1 land but managed to topdeck another one next turn and reveal all my creature while my opponent showed Geist of Saint Traft as a chump blocker
Round 3: 1-2 Loss. Big Naya. First game I won in 4 turns, but then he sided Loxodon Smiters and Boros Reckoners and my pressure became useless on turn 3 Reckoner and turn 4 Unflinching Courage while having another Reckoner and late Smiter as a blockers.
Game 3 I mulliganed to 6, then to 5 and had to start without white mana, and I didn't see white lands till end of a game.
Round 4: 2-1 Win. Simic Evolve HexPants. My opponent piloted deck with Experiment One, Cloudfin Raptor, Strangleroot Geist and Geist of Saint Traft. First game was very quick, I simply overran him. In the 2nd game he showed Smiter turn 2 via Avacyn's Pilgrim and gave him aura with +2/+2 and flying and it was a game. Game 3 I mulliganed to 5 and starte with Sacred Foundry, 2xChampion of the Parish, Mayor of Avabruck
Flip and Ghor-Clan Rampager.
Turn 1: Land, Champion, go
Turn 2: Topdeck another Champion, second Champion on the table, swing for 2
Turn 3: Topdeck Boros Elite, 3rd Champion, swing for 5
Turn 4: Another Mayor, put Boros Elite, swing and being chumped blocked
Turn 5: Thank god!! Rootbound Crag, land, atack, bloodrushed Champion with 3 counters blocked by Strangleroot Geist, win!
