Hi Smmenen,
First thanks for the article, I love when you get out of known archetypes to write about others options. I think this is the kind of things that are needed to get new ideas to bloom, without them only restriction/unrestriction/new set seeing printing would give vintage changes.
As for the use of bitterblosssom in suicide black I can't help it but to go back at what Edward was saying about the Zombies:
Let’s imagine that I cast a Carnophage on turn one. By the end of the fifth turn, the Carnophage will have done eight damage. A different scenario: Let’s say that I was busy disrupting my opponent, and I couldn’t cast my Flesh Reaver or Nantuko Shade until turn three. By the end of the fifth turn, I will have done the same amount of damage with a Flesh Reaver as I did with the Carnophage that had a two turn head start! Similarly, Nantuko Shade will almost certainly deal at least eight damage in such a scenario - and in both of these examples I gave the Carnophage a head start just to demonstrate how much slower it is than the optimal creatures! So as you can see, the illusion of dealing more damage faster with Zombies is merely that - an illusion!
Since bitterblossom, even if cast on turn one, would have only done 6 damage by the end of the fifth turn, this is even less than Carnophage witch is the example used by Edward in his primer. I would like to know why you think this is fast enough for vintage and help you put you opponent on a clock? Even an Ashenmoor Gouger casted on turn 3 would have done more damage by that time. I see the added value against Staxx and the combo with Gate to Phyrexia. If you would have had a splash for green with Tarmogoyf I would also have seen the fact that this is a +2 as counting as a Tribal and an Enchantment cards but even with that I don't see the need for it. Could you elaborate on this choice.
Regards
My assumption would be that, even if Blossom is slower than, let's say Carnophage, it is a lot more resilient as a threat. While creature removal isn't a big factor in Vintage, bounce and other creatures still are, and anything that can be answered in the red zone is worth less than something that can't. A CoV targeting Carno buys you 2 full turns of no damage. The same CoV employed against Blossom itself buys you 1 turn.
Also, two Blossoms are nuts. Two Carnophages are not.
