So, all the blue decks where just killed, and most combo decks where greatly weakened...so whats left?
Decks that are completely untouched by this:
Ichorid
Stax
Workshop aggro
WGDX
Belcher
Landstill (I think)
Goblins - Not that good, but might be playable now that decks are slower
Decks that are touched but not exactly killed:
Control slaver - Sure brainstorm was really good, but really? The main engine is untouched and it's got a good match-up against workshops which are probably on the rise now.
Hulk smash - Again, brainstorm is the only major loss, however...IntuAK is looking good again, so maybe it can come back in the light?
Sensei Sensei - Maybe this will be fast enough now, although resolving future sight is probably still pretty tough!
Long variants - Still got amazing turn 1 plays, but they aren't nearly as consistent.
TNT - Really should be in the above categori, but it hasn't been played for years...If oldschool control rises, this might work out.
Keeper - Do i dare say it? Yes i do!

If no other control deck proves to be superior in all aspects this old horse might be back.
Angel oath - Can't rely on brainstorm to shuffle back the baddies, but still got a very powerfull early effect.
MSPaint - Well, might be dead, but really...it might be able to replace the draw engine...And while red blasts might be weaker, i think there'll be lots of blue spells.
Suicide - Highly doubtfull, depends upon how much the meta slows down.
Fish - Probably worse then before, as the decks fish preys on just got weakened and thus probably less played.
Bomberman - I don't think this deck was all that dependant on brainstorm, as there generally are no real dead draws.
Decks that are dead:
GAT
Flash
Tyrant oath (As far as i know!)
And i have probably missed alot of decks.
Don't despair vintage players, i think this is a great time! There's lots of decks and cards to play with, and now we actually have a choice in draw engines..
An example:
IntuAK - Probably the fastest non-bazaar engine now...
Thirst - Blue, works with artifacts.
Skeletal scrying - Slow, but does alot if it resolves
Dark confidant - Worked before, and now everything is slower and the average mana cost in decks probably just dropped since gush isn't there anymore.
Night's whisper - Might suplement any of the above engines...And possibly replace brainstorms in ways of getting mana.
What does everyone else think? I am overjoyed, i have been looking forward to alot of this, although i never expected them to take away brainstorm, and much less ponder.
I'll have to end now as my laptop is running out of power, a final word:
It's time to bring back old favorites and make new ones!
