Improving that Binder: MTG Price Speculations

Below are are few highlights of the cards I heard the most about at the trading tables.  I've included some of my speculation on the cards.   
Stoneforge Mystic - Worldwake Rare
Current: $20-25
Trend: Stable, to down.
If you can pick these up via trade for $15-20, but never over $20.  If you are shelling out cold hard cash for these at the moment, expect to pay the full $20 at most brick and mortar shops.  I would advise against this option, as they will most likely settle down around $15.  Remember, Worldwake was one of the most opened sets in magic, so there are ALOT of these on the secondary market.  Right now post PT and potential UW brews in extended are keeping the price up. 

Sword of Feast and Famine - Mirrodin Besieged - Mythic Rare
Current: $15-20
Trend: Stable to up.
The pro-blackness is the sickness.  This card is hot right now.  Second most sought after card in the local meta.  You only need one to go with your Stoneforge Mystic.  If you do not have one, pick one up ASAP.  If you can pick one up in trade from $15-20, do so.  This card has plenty of potential in extended this season(and seasons to come). 

Inkmoth Nexus - Mirrodin Besieged - Rare Land
Current:  $8-12
Trend:  Down
This guys hasn't found a home yet.  While fun with Tez, just isn't getting there very quickly.  This was preselling at 12-14, and has seen a small price dip.  I would expect this to continue until someone post good results with this in standard or legacy (the two places with the most potential for this card).  Even then, only expect an upswing to around $10. 

Tezzeret, Agent of Bolas (Planeswalker) - Mirrodin Besieged - Mythic Rare
Current: $45-60
Trend: Down Down Down
If you have extras, now is the time to liquidate and pick up later.  This guy saw a huge jump because of new brews at the PT and a rush to get 4 of by everyone subsequently.  Over the PT weekend they saw a jump from 35 to 40 to 50 to sold out by most major sites and stores.  The price jump was only due to demand.  As more MBS packs are opened, there will be more and more Tezzy's available.  Expect another Gideon situation.  I am stamping this one to hit a bottom of $25.  This will all change if there are legacy or vintage implications.
