This is deck I'm using in the KC cup, and I'm doing really good =) (around 900 now)
2x Element Saurus
3x Crawling Dragon
3x Two-Headed King Rex
1x Kuriboh
1x Sergeant Electro
1x Basu
2x Riryoku
2x Order to Charge
1x Twister (Not sure about this one - but I have no EC)
2x MirrorWall
1x Windstorm of Etaqua
1x Magic Trammer (love this one - helps against ritual/fusion ,Twister&co, BigWaveSmallWave, Riryoku,...)
I also tried Metalmorph, TrapJammer, Michizure, ... but I like the Spells and Traps now.
What I really like to include is an EC, and a 2nd Kuriboh... I'd really like to combo them with Tragedy..
