Yes I admit that the good old ash tray maker is a strong part of the CS build however they are not the heart and soul alone. the beauty of slaver is that is can win with or without Welders, and with or without mindslaver itself.  Understandably with a bit more creativity or brute force, but none the less they are not all the deck has to offer.

Alot of decklists over time have opted out of running the 4th welder for many different reasons.  And quite a few of those reasons have to deal with offering a more diverse maindeck in order to provide more solutions to little (or big) problems or just ways to get to what you need.  Im not bashing you for questioning why only 3 welders. Its just that Ive found that that slot oppened up by the removal of the 4th welder has left the deck a little leaner and due to the lack of direct search removal (i.e. cranial extraction etc.. ) currently being run its not as if the welders are in that much jeopardy reguardless of where they are.  Now I know that they will most likely eat a swords or 2 through the course of the game or fall pray to the sharpened dart of the Trike. But another thing that I have noticed is that alot of my opponents play around the 4th welder as if he is in the deck.  There is a bit of misdirection going on becuse they will assume that Im runing the 4th or whatever and yeah I know that when I see the 3rd welder hit the yard that Im not going to randomly see one rip from my topdeck or anything however my opponent doesnt.  Ive had several situations where my opponent held a swords  while my trike gave him a total of 11 points of dammage over a few turns, all due to the fact that he didnt use swords was afraid of the mighty welder that wasnt.

As far as gifts go, I think its a great card with alot of options that most of us all know however Im not sure if I could accept it as more then a 1 of in slaver.  Personally I dont run it, never really cared for it.  I prefer direct draw and mannipulation of library through tutors.  I feel that cards in the hand are better then cards that go straight to the grave because they atleast have the chance of being played twice.  <3 Yawg Will   <3    But any way thats how I feel about that.
