[/deck]
1. Game vs. B/W Midrange (friend of our playgroup) - 2:0
1. Round: It was
a quick and dirty first round, burning him down without any problems. Had some pretty good draws.
Boarding: -4 Shock, -4 Skullcrack, +1 YP$, +2 BO, +4 Cackler, +1 Revoke Existence
2. Round: Had a pretty good start with AZ and Cacklers. His desecration demon was permanently tapped thanks to YP$. This round was also very quick and dirty
2. Game vs. RW Burn - 2:1
Was a little bit afraid, because I have to experience since our playgroup doesn't play any burn or even aggro deck.
1. Round was like AZ vs AZ, CP vs CP, Magma Jet vs. Lightning Strike, Charm vs. Shock, but than my helix hitted together with 2 CP taking him down.
Boarding: -4 Skull Crack, -4 YP$, +4 Cackler, +2 BO, +1 CttR, +1 Spark Trooper
2. Round: Mulligan down to 5, than I was flooded. Had no chance to recover. At the end I got Spark Trooper, but it was already to late.
No Boarding:
3. Round: This time my opponent was flooded.
Funny was, I had BO online. He was at 4 life and casted Spark Trooper, attacked, began to add lifepoint until I reminded him on BO ^^. Ended the game with 20LP
After this game we talked about the deck. He had the usuall decklist from the last tournaments and was quite impressed about the decklist you guys figured out. Started to watch another RW Burn playing with the same decklist as his.
3. Game vs. Mono Red Aggro - 2:1
1. Round was a race, which I won with 8 life.
Boarding: -4 Skullcrack, -3 YP$, +2 BO, +4 Rakdos Cackler, +1 Spark Trooper
2. Round started real good for me with a solid start. Got 2 cacklers and burned his 2 cacklers in one round with 2 shocks. But I got no white manasource until this turn (played sacred foundry tapped), leaving me with 1 helix, 1 charm and 1 spark trooperon 13 life. In his round he got me down to 2 life with a lot of creatures and burn and than he played
Mindsparker -__- and I couldn't play my helix or charm
without dying. My trooper got me back to 8 life but this didn't change my faith. Lost while he was still at 12 life.
No Boarding.
3. Round: pretty solid start for me and got him down in 8 turn, while I was back to 20 lifes thank to helix.
4. Game vs GRb Monster - 1:2
It was a young player, but with a lot of tournament experience. Know him from the last FNM and he is regulary top placed at the FNM.
1. Round: Veeery good and hearth beating round. He won with 3 life. I was shortly ahead but then he top decked SBD and attacked with him, one reaper and some smaller creatures.
Boarding: -4 AZ, -4 Shock, -1 Skullcrack (since he had Nyleas Disciple) +2 BO, +2 Mizzium Mortars, +1 Fated Conflagration, +1 YP$, +1 Spark Trooper, +1 CttR, +1 Assemble
2. Round: Got BO online very early, burned his elfs and slowing him down. He got 2 Domris but couldn't find any creature. Won this round with 16 life.
Boarding: no Boarding
3. Round: man... this was one of the best games I ever had. It
was an up and down on both sides. He got me down to 5 and I cast helix and trooper going back to 15 and swing with my creatures leaving him at 7. He stroke back an put me to 4 life, leaving me without any chance to defend me in his next turn. My charm putted him down to 3. My draw... had a lot of outs, because I had not draw any Strike, just one skullcrack and 2 charms. But I draw a mountain and he won. But still one of the best games I had in the last time

Thoughts after: My biggest problem were his planeswalkers. I was never sure to burn them down or attack him. In the 3. round I was forced to keep his domri down, so that he can't fire his ultimate. But after the game I ask myself, if I shouldn't have burned my opponent directly. Maybe this would had won me the game? I don't know.
5. Game vs. Golgari Midrange? - 2:1
1. Round: Both of us had a solid start, but he wasn't sure about my deck
and didn't know at first how to play against burn. Won it with leaving me at 14 life.
Boarding: -4 AZ, -3 Shock, +1 YP$, +1 Spark Trooper, +2 Mizzium Mortars, +1 CttR, +1 Fated Conflagration, +1 Assemble
2. Round: Mulligan down to 4 and I couldn't real get back to game. Lost this round with him at 7 life.
Boaring: I wasn't sure if my boarding before was correct. Should I play the creature plan and try to overrun him early or should I try to burn him down and stabilize the game with YP$, BO and Assemble? Decided to stick to my first boarding and didn't change my deck.
3. Round: This time he was flooded and this round was ended within five turns.
Made place three out of 31 and I am veeeery satisfied with this deck.
But I am sure I made some mistakes, especially with the boarding

Since I don't play online, I can't play that much magic as I want and test. So I participate the forum and enjoy watch your Videos,
for which I am very thankfull
SB thought:
I think I will put out Fated Conflagration and add maybe 1 Glare of Heresy.
