Alright, I took this baby to cities, because outside of my Honchkrow deck, it's the only deck I feel really comfortable playing (I can play Machamp/Gigas/Kingdra/Scizor decks well, I just find no appeal in decks where I don't have to think and have no solid lines of recourse.)
Here's what I ran:
4-2-3-1 Dusknoir
1-1 Bronzong
1-1 Claydol
1-1 Azelf
2-1 Uxie
3 Unown G
1 Spiritomb
4 Roseanne's
4 Rare Candy
4 Bebe's Search
3 Night Maintenance
3 Poke Radar
2 Warp Point
2 Moonlight Stadium
1 Luxury Ball
1 Premier Ball
9 Psychic
4 Call
Not precisely your list, and not my ideal list either, but I couldn't nab the Cressy X, and so I figured I would go with this.
Round One: ____ Sizemore
I remember the kid distinctly, I just don't remember what he was running. Textbook quick Dusknoir, damage evening the KOs.
1-0
Round Two: ??? - Skittles
I had talked to his teammate before the game, and his teammate said someone was running skittles. Once I saw the Ho-oh hit the deck, I got really nervous - I'd never even seen the deck in operation, so I wasn't sure what to do. MY third/fifth turn, I pokeradar. I was going to tutor for the Bronzong and DP Dusknoir. I PokeRadar'ed, getting FIVE CARDS. It was nuts. That clinched the gameDamage even sniping and his repeated play into dark palms made for a long game. He had a togepi sitting on bench, and after a few turns I figured he had a Togekiss in hand, waiting to draw the RC. I sniped that, drawing my fourth prize, and he drug out another five minutes of game time as I nabbed the last two prizes.
Round Three: Mike R - Dusknoir (mirror)
This was ludicrous. Mike's really good, and I played this matchup at league (albeit with DuskCor at the time) and he dominated me. I get a crappish start, with some decent trainers: lone Bronzor. I call heads, it shows up tails. Kaching. His turn, flips over Duskull, call energy, calls, go. My nominee for the most epic turn one EVER involved the following: two poke radars for three apiece, two T1 Shadow Command Dusknoirs, and an Uxie. When my turn finally ends (it was literally a 5+ minute turn), he keeps moaning. It looks like I've got the win locked. I make a stupid move: rather than nightspin his Unown G'd Dusclops, I damage even KO a benched Uxie. So he hits his second energy drop on the Dusclops on his turn, evolves it to Reaper Pulse Dusknoir.
With a G'd claydol bench and a g'd dusknoir active, his lone Reaper Pulse Dusknoir singlehandedly convinced me of its utility. Even with Dusky X on table, he was cleansing away that damage, decimating my entire lineup. He 'Dols into a moonlight, plays it, rolls head for Dark Hide, and seals the game.
2-1
Round 4: Some PokeMom with Dusknoir
I knew this was going to be a stale game when she told me she was running Dusknoir, then asked what my Unown G was. Systematic board control kept my small errors from giving her any ground.
3-1
Round 5: Ben Thompson with Raichu/Electivire
This wasn't even a game, really. My opening hand was Bronzor, Psychic, Night Maintenance, Moonlight, 3 RCs. He mulligans. Bronzong. He mulls again. Fourth RC. The worse hand ever. I topdeck a Roseannes, picking Uxie and Duskull. I try and play all my RCs choosing no basic, same thing with Night Maintenance. Apparently this is unallowed, and since I had dropped the Uxie and began drawing before Judge got over, I ended up Uxieing for 1.
I've played the deck out of bad starts, but that was in a league of its own.
3-2
I come in eighth out of twenty-six. Mike R and the Ben Thompson kid both go on to make the top cut, Mike winning everything, thus avenging my death - if only he could do the same for my rating.
After the tourney, I switched over to 1/1/1-1 Dusknoir line, because when the spread tactic doesn't come into play, this deck needs oomph - against an Unown G'd deck, I've got nothing. 70, snipe 20, heal 20 for three isn't too bad, coupled with the PokePower (what, you tutored for Claydol last turn?).
I don't see a need for counting song Duskull in my list - the speed of Duskull --> Dusclops I felt clinched crucial tempos within my games. However, I also didn't think that a Reaper Pulse was superior to a Shadow Command, and I've since changed. (Side note, your list has no 'Dol, so the Commands might be more crucial therein). I'm not sold on the Azelf Lv. X - I only used it once. However, I have a limited game sample, so I'm fairly confident it's staying.
Anyway, it's 1:15 AM my time, and so I'm going to bed. I'll post tomorrow when I finalize a decklist with the Cressy X I traded for.
