My build differs from the original versions a bit, but all changes have been made as a result of a lot of playtesting in tournments and with friends. I cut the conclaves completely because they just weren't getting it done for me. Most of the time they set me back a turn because of the comes into play tapped ability. When I had it in play they seemed to be just too mana intensive to be effective. I put in more fetchlands in to fuel my lavamancer, and get me the colored mana I need. Other changes include the 1 md Crucible of Worlds, but I'll talk about that a bit later. I also cut a Cloud of Faeires and 2 Voidmage Prodigies for 3 flying men, which has been working pretty well for me. (I recieved this suggestion from David Ochoa btw) Not only are they still pitchable to Force of Will, they can come out turn one, and begin the beats turn 2 (hopefully with a curiosity). Other than those changes the deck is pretty standard. Now, to get to some specific points from covetous;
Where does Crucible fit into this whole plan? Is it good enough to MD, considering the dirty things you can do with it? If so, how many should you MD, one or two?What should come out to put the CoW in? Should it be SB'ed instead, or not at all?
As reflected in the decklist I have tried one Crucible in the main, and it has done wonders. It has won some games for me all by itself, and definately warrants at least 1 md slot, if not 2. In my build, I simply cannot cut anything else, but if I could it would be for another Crucible most likely. Having 1 md and 1 sb has been fine for me. it usually goes in for the mirror, and versus other slower decks, ie. tog. It isn't too good versus fast decks because fish isn't fast enough to use it effectively.
Who wouldn't run LoA in Fish? It's restricted for a reason, you know...
Haha, maybe he just doesn't have one?
If you need to MD Fire/Ice as more than a random one-of (and I still don't think there's room for that), then play something other than Fish because your meta is too aggro for Fish to be a good choice.
Yea, I totally agree with you here, actually the one md Fire/Ice is the card I cut for crucible. however, I do believe it merits a sb slot, because it is absolut house in the mirror, and it's effective in the FCG matchup as well.
Well that's all for now, I'll check back later to see what's new in this thread.
