Ok so Kind of off topic, but I read MaRo's Article today, and he said something I found very, very interesting.0_0
EDIT -
I just read the flavor text. RIP Isperia.
Mark Rosewater said:The Creative team then split the guilds in half. Five would fall under Bolas's influence, and five would not. (Although, I should point out that each guild has elements pulling in both directions.) The five guilds that fell to Bolas would each have a planeswalker, beholden to Bolas, who would lead the guild. The creative team spent a great deal of time picking which five would fall to Bolas. Their choices were swayed a lot by the story that they wanted to tell.
So, if I'm interpreting this correctly, then half of the guilds will fight for bolas and half will fight against. Providing that the guild war is color-balanced, then we know which guilds in the next set will be fighting for bolas:
Orzhov
Azorius
Gruul
This may seem like a weird mix, but stop and think about it for a second.
-The Orzhov like money and their leadership is already made of ghosts. Why wouldn't they side with bolas?
-Vraska appears to have just killed Ispera, so Bolas can install a planeswalker pawn.
-Gruul likes to say "Crush them", "We Eat", and, in general, just watch civilization crumble around them. Bolas could help them with all three of those things.
So, then, what about the Izzet, Golgari, and the guilds that didn't join bolas?
Izzet- Even though Niv-Mizzet will probably fight against Bolas, he's away with a research project right now, so Ral is leading the guild. Ral is a pawn of Bolas, so it's obvious they would join him.
Golgari- If you read the Ixalan story the reason they join bolas is pretty self-explanatory.
Dimir- The Dimir want to be the ones pulling the strings. Bolas also wants to pull the strings. String-pullers don't get along too well.
Simic- Although it's purpose has been twisted, the Simic guild originally was formed as a health department of sorts. Bolas is known to be very un-healthy.
Boros and Sylesnya- they're goody-two-shoes guilds without any strings to be pulled at this time. Killing Trostani or Aurelia probably wouldn't have benefited bolas in any way, and as such are not being manipulated.
Rakdos- These idiots are too crazy to be controlled, even if they do like to watch the world burn.
This "color-balanced-war" thing would make sense for draft in the spring set. Since all 10 guilds will be represented flavorfully (just not fleshed out), it would make sense that draft would represent the war. I think the evidence we have supports this theory. If you look at the cover of the "Ravnica" novel, you can clearly see what appears to be a new U/W PW and Kaya, Ghost Assasin
I think these guys are going to be taking over the Azorius and Orzhov guilds respectively. It especially makes sense if Kaya is in charge of the Orzhov since she is a known Ghost-Slayer and probably killed the Obzedat.
Just some random (time wasting) musings on my part.
