I do not believe this "discussion" has a side. I am with @jaco on this since I also own all of the cards and I try to play everything. I think the discussion around Mental Misstep is very interesting since I do see valid points on either side.
Being honest, I traded my workshops away back in 2004 and I just bought a new playset this year. The reason I traded them is that once Trinisphere was restricted Shop became a very boring deck and I need a Lotus so I traded for the Lotus.
I look at Shop now and it looks fun. The difference is the transition from Prison/Control over the years into an Aggo deck. I play at RIW Hobbies and for the past year 2 Card Monte has been heavily played and that is a Shop combo deck.
I do not see an issue with meta game but I do see something interesting with players and their choices, especially when it comes to Mental Misstep.
