I have the corrected decklist below, and a short tournament report. Sadly, I lost my notes, so I'm working from memory right now.
Round 1 vs. Ariston Go (RG Beats? Fish? Bombs Over Baghdad? I really didn't know.)
Game 1: He won the roll, and I had one of my most horrible draws ever. I mulled to five and never found a land until I believe turn 3. I was stomped by a Mongrel with a Jitte in its mouth.
Game 2: I went first, and took my time since I had lots of draw spells. I comboed out via Plan C on turn 2 or 3 using Rituals, a Lotus, and a Demonic Tutor grabbing Will to replay everyting.
Game 3: Essentially the same thing as Game 2 happened, pretty much. I don't remember casting Doomsday in any of the 3 games.
Round 2 vs. Mike Ongkeco (Sui Black)
Game 1: He opens with a Dark Ritual. I force. I open with a Doomsday. I win the turn after.
Game 2: He opens with a Dark Ritual. I force. I play Doomsday two turns later. Same thing happens.
Round 3 vs. Mike Limosnero (Oath)
Game 1: I combo out on turn 2 with Pact of Negation and FOW backup via Plan C.
Game 2: I combo out on turn 4 with FOW backup via Plan A... except I cycled into my stack, I believe.
Round 4 vs. Mondu Quiambao (Worse Than Flash)
Game 1: He opened with land, Lotus, Counterbalance (FOW), Counterbalance (Good.). I take my time to dance around it as he only had one land ever, and bounced it EOT then comboed out via Plan C.
Game 2: He kept me locked out via Top/Balance. Dark Confidant beatdown FTW!
Game 3: I Duress his Top. Nothing of consequence happens, then I combo out on Turn 3 via Plan C with FOW backup.
Round 5-6: ID, as my team decided to devote some time to our Greek Deity, Testi-Cles.
Quarterfinals: Vs. Allan Esguerra (Manaless Ichorid)
Game 1: Allan's dredging was horrible. I protected my hand, then cast Doomsday on turn 2 for a Plan A kill on turn 3. He only ever encountered one dredger, meaning his only attackers of 2 Ichorid weren't going to be enough to stop me. He cast Therapy and missed. His only hope was a Chalice for 0, but I modified the stack I setup so I would be able to dance around it since I expected Chalice for 0.
I set up:
Incidentally, I was holding a Wraith, so since I was down to 3 after Ichorid x 2 attacked me, cycling allowed me to get the top four cards of my library, resulting in a Desire for double Tendrils win.
Game 2: I opened with a Leyline. He had nothing against me as after he went first after mulling to 4, I plopped down LED and then cast Doomsday for a turn 2 win. He couldn't find chalice, thereby sealing his fate.
Semi-Finals: My teammate, Ching Parungao, scoops in my favor. Kudos to him.
Finals: Vs Glen Cariaga, Hulk Flash
Game 1: Silly me. I didn't Cycle into a turn 3 combo when I had the chance, so he comboed out the turn after I passed to him. It was dumb of me because the topdeck was a Dark Ritual, and I had Cabal Ritual, Yawgmoth's Will, and Demonic Tutor in hand already.
Game 2: I locked him out with Leyline. But when I Duressed, I took a C.Spell. Should've taken Lotus. He later hardcast Hulk and killed me with it, thereby ending my amazing and enjoyable run in this tournament.
