Quote from BlueTronFTW »You gotta give me more than "would bring other things in its wake." This is why I'm always concerned about bans or unbans short of Eldrazi Winter situations - odds are nobody can accurately predict the full ripple effect.
This is pretty true. When they announced the Gitaxian Probe ban, people claimed Death’s Shadow was dead and that Infect would be okay.
Here we are much later and Death’s Shadow had already starting to evolve into a midrange deck and the Zoo-style version still puts up results now and again. Infect on the other hand? Well, Infect has done zilch since then. (Of course, the printing of Fatal Push also helped sway some of that as well).
I also remember people clamoring about how great the Thopter-Sword combo was going to be, and how it was going to reshape control when Sword of the Meek entered Modern play. These days, people don’t even mess with that card outside of fringe brews because there are better, less fragile win-cons.
Remember Ancestral Visions and how it would make Jund unplayable? Not so much. A combination of Death's Shadow being the seemingly better midrange deck and Eldrazi hanging out in the format pushed Jund out.
People (myself included) generally use their own biases to overestimate and underestimate the impact that adding or removing a card from the cardpool will produce. WotC has a track record of being quite conservative with unbans. If we get unbans, I’d probably bet that it’s not going to make a huge impact on the format.
