Check this deck which I was working on with my 2 friends. It was tested in real-life dueling and it was able to beat Zombies (T1 deck in those times) during tests. It's the original one, but I'll point my personal corrections.
Monster (21):
3x Armed Dragon LV3
3x Armed Dragon LV5
2x Armed Dragon LV7
3x Masked Dragon
2x Flying Kamakiri #1
3x Silpheed
2x Twin-Headed Behemoth
1x Sangan
1x Spirit Reaper
2x Slate Warrior (I gues we've put it as a total random...) -2
+1 Morphing Jar
Spelle (11):
2x Level Up! (I'm not a fan of this card, because it's quite situational - try running Shrinks, they're more functionational and also help Armed Draggys to survive 1 turn :]) -2
2x Rising Air Current (this should be definitely changed (maybe Scapegoat?) anyway) -2
2x Creature Swap +1 (this deck has many searchers, with SG it'll be working perfectly) +1
1x Heavy Storm
1x Monster Reborn
1x Mystical Space Typhoon
1x Swords of Revealing Light
+2x Shrink
+1x Card Destruction (got problems with 3 Lv5s and 2 Lv6s on first draw? This can be quite useful!)
Trapy (8.):
3x Waboku / Threatening Roar (Threatening Roar of course is better)
2x Sakuretsu Armor (You can change it for Dimensional Prison in-game, but in real life that's definitely cheaper option ^^)
2x Bottomless Trap Hole
1x Torrential Tribute
I guess that this one will be working pretty good =]
