I bring this up in part due to the latest episode of Constructed Resources, wherein Jon and Marshall discuss these two cards with respect to the rest of the banned list. The guys spent some time talking about how, in general, cards that let you cheat on mana are most often the ones banned. For example, if you take a look at the Modern banned list, many of the cards on the list are banned because of their ability to cheat on mana costs or provide mana at too fast a rate (Bloodbraid Elf, Chrome Mox, Rite of Flame, Seething Song, Stoneforge Mystic, the artifact lands, etc.). Far fewer cards are banned based purely on power level (Jace, the Mind Sculptor, Skullclamp, Umezawa's Jitte).
Part of playing Magic is enjoying playing with powerful cards. So when R&D has made a major banning that impacts your favorite format, do you generally react with relief? Or would just assume continuing to play with those powerful cards?
Maybe this is too generalized a question. When Jace, the Mind Sculptor was banned, everybody who owned copies was probably angry and everyone who didn't was thrilled. Obviously, a banning that impacts an expensive card is more polarizing than a banning of say, the Mirrodin artifact lands, which were printed at common. I'm sure a few people were upset at that banning (maybe Affinity was their all-time favorite deck), but for the most part, that has less of a financial impact on the playerbase.
Regardless of particulars, I'm interested in how you generally view bannings. Do you think they represent a failure on R&D's part? Or do you look at it through the lens of wanting to play with good cards, and knowing occasionally some will be too good? Does it all just come down to how much money you lose? When are bannings the right thing to do, and when do they overreach? Share your thoughts in the comments.
