your post indicates that the pitching of fow involves discarding something. This is not the fact: you must remove a blue card from the game. I'm sorry if its my fault, but it really looks like that is what you mean.
Sorry if that was confusing. I was thinking that a Standstill in hand could be pitched to FoW. Whereas the breaking of a Standstill at eot (what is often the game plan against the card) would allow me to discard an artifact (if over 7 cards in hand).
I have problems including a decklist since I think that the inclusion of standstill would change the contents of the deck drastically. I'm simply trying to illustrate what (if any) synergies exist with welders and standstill. For example, I go Workshop, Mox, Mox, Smokestack, Welder (a strong yet reasonably common opening). Following turn, I drop a Standstill. Or to make it more reasonable, drop the Welder and the standstill on the same turn during some point in the game. I can then use Moxen to recur whatever may be in my yard, allowing me to recur threats while the opponent works around the standstill. Another example would be to slave and then drop a standstill. It's a 2cc Ancestral in that example. (albeit that example is much weaker given that an active slaver is a solid step towards game over).
as opposed to protecting your welder, why not just go for the win?
I'm a huge fan of the slaver and stacker builds (been playing them since I got my first workshop last August). Neither goes for a quick finish, usually planning on a 5 to 6 turn game, minimum. Personally - in my meta - I need to plan for a long game and deal with Swords to Plowshares and Fire/Ice mainly, Gob Sharpshooters and red fishies occasionally. I rarely see either of the black cards mentioned.
