or is the new structure, invincible fortress, the most tourney worthy with slight modifications? what would you guys suggest for replacements. while keeping the theme of defense and burn? the combo of giant rat after getting effect and summoning criosphinx with two other face down monsters and Exxod in your hand? I think adding tsukoyumi would be your first move. what next?

They're not supposed to be tournament playable right out of the box. They're just meant to be able to get a duelist started out by having the deck to be able to used in duels.

ALL The structures are capable of being tournament worthy with modifications, but the "most playable" one is most likely the Spellcaster Structure one. Burns more quickly, plenty of burn support AND good Spellcaster support as well.

hmm.... you said earlier that staples were bad... now you say that spellcasters are good because of the staples...i.e. breaker.......what deck do you play????

now, on topic, rock is good. the wind one will be better.... i think. but my favorite is the zombie one. it hardly needs any modifications.... also, i hope the new dino deck is good...

Ummm...try actually reading my post and do some thinking...

Breaker IS Spellcaster support which is why he DOES fit in. I don't think "staples" are bad at all just not NECESSARY for EVERY single Decktype. YOU'RE the one who only assumed I meant that.

I'm with HDI, spellcaster by far the most playable. Splice in some TToC and an injection fairy lily and you have yourself a very playable deck. After that you can easily change it by removing the ones you don't use often, like blast magician etc, and replace them with more beatsticks (second myhtical beast, second rapid-fire) an extra dark magician or dark magician girl, or some support cards like old vindictive.

I find this new SD too hard to be really playable. But with some changes, you could turn it intoan exodia support deck I suppose, if that's your thing.

I found all SD's very good, when tweaked. Zombie certainly needed as many tweaks as the others, patrician of darkness, vampire lord etc. And I personally found both fire and water, once tweaked, played a lot stronger than any of the other decks.

if you talk no tweak or minimal tweak, then spellcaster takes the crown. I found the warrior deck least playable.

Once the Wind Structure is out, you'll find that one to be the least playable...people will really only get it for the new stuff to collect and/or for the common Slate Warrior and such.
