At school today, me and my friends from track were thinking of a wave motion deck that could also use final countdown. Here's what we came up with, and see if you could suggest anything else.

Monsters:
3x Golemn Sentry
3x Hane Hane
2x Man eater bug
2x Swarm of Scarabs
2x Guardian Sphinx
1x Jinzo
3x Raging Flame Sprite
1x Spirit Reaper


Spells:
3x Wave motion Cannon
1x Swords of Revealing Light
3x Final Countdown
1x Level Limit Area B
3x Scapegoat

Traps:
3x Wall of Revealing Light
1x Gravity Bind
3x Sakuretsu Armour
1x Torrential Tribute
1x Mirror Force
3x Waboku

Try it out on Yugioh World Championship 2007, or if you have the cards. I think this could make for a fun deck:D

Drop: 24

3x Golemn Sentry
3x Hane Hane
2x Man eater bug
2x Swarm of Scarabs
2x Guardian Sphinx
1x Jinzo
3x Raging Flame Sprite

2x Scapegoat - you can only run 1 copy...

3x Sakuretsu Armour
3x Wall of Revealing Light

Add: 24

3x Gellenduo
3x Nimble Momonga
3x The Unhappy Maiden
3x Winged Kuriboh

3x Nightmare's Steelcage
3x Messenger of Peace

3x Threatening Roar
3x Thunder of Ruler

This will give you a more streamlined build that focuses on it's goal: To stall until you win with one of your two win conditions.

any more thoughts would be appreciated. BTW, do you guys think this is a good concept?
