Quote from spawnofhastur »RG Scapeshift as a deck has only really existed for two years, mainly because while Twin was around, it was incredibly terrible; once Twin disappeared, we could drop the blue from RUG Scapeshift and focus on being more all-in.
This statement is exactly why I spent nearly two years complaining about the Twin ban. It was likely the single largest contributing factor to the exponential increase of all-in, linear strategies. So much so that even after multiple other bans (Probe, GGT), it's STILL a problem because no reactive/control/tempo deck can deal with so many different levels of linear degeneracy as efficiently as Twin (and do so without ever holding an oppressive share of the meta).
We all assume nothing will change until after the PT. Hopefully then they will realize how much they have F'd Modern and give us Twin back at that point. Hopefully along with other cards that have no business being banned like BBE and SFM.
