Why did I create another B&R thread? Because I'm afraid this suggestion will be lost in the discussions. I have been Brainstorming since Dream Halls and Time Spiral were Standard-legal. Brainstorm wasn't as good then as it is right now because of the lack of shuffle effects, there weren't any fetchlands and Brainstorm is basically the only filter spell available.
There has been much talk going on since 2011, during the Snapcaster Mage and Mental Misstep era, that blue decks are dominating the format. Mental Misstep got axed, but B&R discussions continued and Brainstorm became the subject of debates. Here's my take on the timeline and how the format gradually deteriorated over time into what we currently see in the DTB section.
2007 - Ponder was printed
2009 - Zendikar fetch lands
2011 - Preordain got printed
2014 - Treasure Cruise printed
WotC admitted mistakes were made: Jace TMS (in standard), Vengevine, Necrotic Ooze, Mental Misstep caused imbalances and corrective actions were taken. Right now, Brainstorm is not the sole culprit. It's the newer cards that breaks it in a sense. We cannot just get rid of Brainstorm because the card puts the format in a balance. Others have already stated that it is a pillar in legacy:
What should "define" the Legacy format? by H.
Without Brainstorm, the format loses diversity as numerous decks will turn into a giant pile of random old/new-bordered cards. Legacy becomes less appealing overall and less interactive since Force of Will also needs this card in order to keep things in check.
Brainstorm > Preordain > Serum Visions is fine, win-win scenario. As I have argued, Ponder has a shuffle + draw effect which makes it stronger than Brainstorm on occasions.
My proposal:
Ban Ponder and Treasure Cruise.
Edit:
So, the thread was deleted by my best bud Jander78 and the contents merged into this one. I was hoping to find out how the community would react to the proposed changes.
I do not think of Brainstorm as a sacred cow, rather as the kill switch to many legacy archetypes.
