While most current storylines relevant in MtG today can be traced back to the time of the Mending and no further (and probably for good reason), Scars & RTR blocks dipped back a little further. My question is: How deep a cut is WotC willing to make in the future to tell a good story? How far back can we expect modern MtG story to have (even minor) threads?
We love going back farther when we can. For instance, we’re doing a Bolas story right now as he goes back quite a ways.
