Ok i personally have a fluctuator deck.  I have been playing it for a year now i believe.  From my playing of the deck, which wasnt agaisnt a field of Type 1 deck, Mainly used in casual play.

I feel the deck needs "memory jar" it is another draw 7 and it helps the combo continue when it stalls. You can easily play it off "Songs of the damned" My fluctuator deck has performed much better with a memory jar in the deck.

Also when creating the deck, I had only like 28 cyclers. It is horrbily incosistent and stalls constantly if you dont run alot of cyclers. I now run 27 cycling creatures and 17 cycling lands. That leaves me with 16 non cycling cards. And depending on your Kill usually leaves you with more open room.

Usually having a land Like ancient tomb or City of Traitors is good for this deck. Especially since all you need is a Fluctator on the board for the combo to start.

But i will get to my point. I personally dont think this deck.  Just meaning fluctuator in general wont be able to survive at all. It could possilby pick up a win or two. But it will be so inconsistent. So many cards can kill this deck really quickly. Chalice for 1 will knock out all dark rits, songs of the damneds. Not only that. This deck can only really run 4 disruption cards. Without losing consistency.

Everything i just said was my opinion. You can take it if you want too. But when i created my own fluctuator deck. I find my chances of winning after turn 2 go down.  And any disruption like a duress, or "force of will" will stop this deck for many turns. So in my final words. I say that this deck will most likely never perform well in a tournament cause of the low % of first turn kills, and low disruption count. It is a fun deck to play , but i dont believe it is a very competitive deck.

First off I am new to the Forums, But i have been reading though the forums for months now. I just never got around to becomming a member.
But onto the Topic of W.W.

In my opinion U/W is probly the most well rounded color base you can have. Meddling Mage is a must, That card is the main reason i would splash blue. That and the drawing.

When going through the previous pages, there was only 1 or 2 mentions of "Mother of Runes" I feel she is needed, this is just me, Especially against combo. Since Combo really only has 1 maybe 2 anwsers at most to like a played "True Believer" or Depending on the type of Combo "Samurai of the Pale Curtain" Having a "Mother of Runes" will possibly stop them in there tracks.

I have to say that the card "Preacher" is awesome. With the large ammount of giant bruisers running around it is a awesome tech card. I dont feel it is maindeck material though.

Most of these designs are very similar though and i wouldnt change much to any of them really. I do like the vial/standstill design. More then skullclamp.

Also i think a great card against combo, Like TPS,Belcher,
any real massive card drawing deck. "Mystic Remora" from iceage, them comboing out can give you the change to just draw up your library also and find a cure to your problem. And they can wait for you to not pay the upkeep but that gives you much more time to set up a lock.

But I really cant say anything else that other people havnt already said.
Maindecking at least 4 swords/4 seals i think is needed. That is my opinion and you dont need to take it.
