This is the deck that I played with this past Saturday (August 2nd) in Nashville. It's virtually the same deck that I got 15th place with in Knoxville. I just changed a couple of things:
Monsters:(20)
2 Cyber Dragon
2 Slate Warrior
2 Kycoo the Ghost Destroyer
3 DD Assailant
2 DD Warrior
1 DD Warrior Lady
1 Exiled Force
1 Don Zaloog
1 Snipe Hunter
1 Neo-Spacian Grand Mole
2 DD Crow
1 Spirit Reaper
1 Sangan
Spells:(11)
2 Reinforcement of the Army
1 Smashing Ground
1 Nobleman of Crossout
1 Heavy Storm
1 Mystical Space Typhoon
1 Monster Reborn
1 Premature Burial
2 Book of Moon
1 Enemy Controller
Traps:(9)
3 Bottomless Trap Hole
3 Dimensional Prison
1 Torrential Tribute
1 Mirror Force
1 Crush Card Virus
Side Deck:
2 Twister
2 Prohibition
2 Light Imprisoning Mirror
3 Royal Oppression
3 Dark Bribe
3 Mask of Restrict
Saturday I lost to 4 decks (3 in the regional and 1 in the win a box tournament): Twilight (Lightsworn+DAD), Volcanic Monarchs, Gladiator Beasts, and Lightsworn.
Honestly, I'm not too worried about losing to Volcanic Monarchs because that deck usually isn't much of a problem for me. I'm just going to chalk that loss up to being a fluke. However, I do believe I have a true weakness for Gladiator Beasts and Lightsworn. I've decided to make some changes to my side deck to compensate for these weaknesses.
New Side Deck:
1 DD Crow
1 Twister
2 Prohibition
2 Divine Wrath
3 Royal Oppression
3 Dark Bribe
3 Mask of Restrict
My biggest problem with Gladiator Beasts is Gyzarus. I already main deck 2 DD Crows, so I think side decking a 3rd one will give me extra Darius disruption. Also, the 3rd DD Crow will help me TREMENDOUSLY against Lightsworn. I'm cutting the Twisters down to 1 again. Most of the time I only side one in for game 2 anyway because I'm never 100% that my Lightsworn opponent is siding in Royal Decree. Not to mention I already run Heavy Storm, MST, and Snipe Hunter main deck to stop Royal Decree. 4 cards to their 2 sounds like pretty good odds to me. I also took out the 2 Light Imprisoning Mirrors and replaced it with 2 Divine Wraths. I have one thing to say about this switch: Phantom of Chaos. I side decked Light Imprisoning Mirrors, Royal Oppressions, and Dark Bribes against the Twilight Deck and lost mainly because NONE of those cards work against POC. Divine Wrath does. DW also works against a ton of other things too. I know that with a toolbox style deck it's bad to use cards that require discarding, but I think that only 2 "discard cost" cards out of a 40 card deck and a 15 card side deck shouldn't hurt me too badly. Anyway, what do you guys think of the changes?
