it's impossible to rate a deck with no theme, lol.

BTW Side Deck's worthless, unless you want to keep something like a couple Dragon Capture Jars just in case.

anyway every deck has to have the 5 staple magic cards: Pot of Greed, Raigeki, Dark Hole, Change of Heart, Monster Reborn.
Then you majorly need good L4 attackers, Gemini Elf, La Jinn, Harpie's Brother, 7 Colored Fish(at least 7 or 8). Then of course Cyber Jar.

Anyway, various deck types:

Beatdown: simple, beat down your opponent. Lots of L4 attackers, then some 2400-2500 attack L5/L6 attackers, and maybe a Blue Eyes or Cosmo Queen if you want.

Rush: L4 attackers plain and simple.

One Turn Kill: name says it all. Unfortunately there aren't many possibilities with this one in the english version so far.

Discard: Force your opponent to discard cards, whether it be from the hand or the deck or both.

Special Win: Destiny Board/Exodia, stall cards, drawing cards.

Control: Now that Dark Necrofear is finally out for english, you can make a decent control deck. Control deck=control opposing monsters.

Burn AKA Direct Damage: Lots of direct damage card. Cannon Soldier's a staple and any special summon cards are nice, + Tremendous Fire, Just Desserts & Ookazi.

Monster Removal: nuke your opponents field. Again, not that many possibilties in english version so far.
