Doesn't it seem a little strange that we all know that if anyone but mjack had unbanned Channex, mjack would be leading a seven-page crusade about how that unban warps the game and makes it an unplayable mess of rock paper scissors that he's already solved before the round began and the unbanner is being ridiculous in allowing their decisions to wreck the game and on and on and on.
He allows himself to ban the most OP card for the fun of it but I don't expect he would allow anyone else that level of whimsy without bringing the forum discussion up to a cat-5 ****storm.
Does someone want me to doomsay a bit. ....... Mkay.
Let's see....... several people are going to try to use Channex. Everyone else is going to be completely **** paranoid to its use, to the point where I expect to see a very large number of decks with things like
city of traitors, storage lands, or anything that means they don't automatically die to channex. My unbanning of Channex has directly warped the next two rounds of vanilla around that one card, and we can fully expect it to be meta-defining. And I knew all of this ahead of time but did it anyways. I wouldn't say any of these rounds have been unplayable, but I again think I have a large part of the meta solved before it's begun.
The card is also "op" to the level where a large part of the above statement is obvious, and I do not have to lead a seven page crusade on the unban because a few other people have already done a fine job of starting one.
Does that work for you?
