nice matches. Your lucky u have Japanese tourneys, I can only play with my *** cards on the net and casual play. *bitchsmacks upper deck* What the hell am I supposed to do with my Japanese cards? Get rid of them cuz a half-assed version of Duel Monsters came out in America? Enough complaining, time to fix ur deck I guess
Magical Scientist?!?!?!?!??!?!?!?! What in god's name is this doing here? Scientist doesn't belong in a Chaos Deck
-1 Scientist
+1 Sangan
Better chance of getting the CED+Yata search lock.
-1 Kycoo
+1 Blade Knight
Kycoo vs. Blade Knight, hmmm... I wonder. Blade Knight > Other L4 attackers.
-1 Snatch
+1 NoC/TT/V Lord
Any of those. Snatch is outdated and all-in-all useless. Most likely u'll give ur opponent a free 1000 LP before they chain MST to destroy it and get their monster back. Snatch would only work for decks that require lots of sacrifice material, and this deck has hardly any need for it.
Otherwise looks good.
