Everyone keeps saying that Tron and Affinity will dominate now. Yeah, everyone said the same thing about Abzan once Pod was banned.
The reason WotC banned Twin was because it was limiting deck diversity. Blue control decks always turned into Twin because having an "I win" button if your opponent ever tapped out turned out to be really good. Now, we might see different blue decks emerge with different win conditions, and maybe one or more of them will stand up to Tron.
So happy with this ban!!!! The only two deck I had a stupidly hard time beating are gone!!! Long live 8-rack
And before I get hate, I understand some players don't like the decision! And I hope they find decks they enjoy as much as the ones they just lost! But I've never Had fun against bloom or twin! A always get beaten in turn 3-4 by them!
