I'm assuming the fifteen extra Dissension cards are all split cards. I believe the most likely setup for fifteen split cards is for each one to be a split between guilds that do not share a color. In other words, two guilds with four total (different) colors per card. There are fifteen such combinations.
Put another way, each split card lacks one color, the same way the Nephilim do. Given a single color, there are three ways to combine two guilds so you get all colors except for that one. Three combinations per (lack of a) color equals fifteen total combinations.
Combinations Without White 1. :symbu:/:symgr: (Dimir/Gruul) 2. :symru:/:symgb: (Izzet/Golgari) 3. :symug:/:symrb: (Simic/Rakdos)
Combinations Without Blue 4. :symbw:/:symgr: (Orzhov/Gruul) 5. :symwr:/:symgb: (Boros/Golgari) 6. :symgw:/:symrb: (Selesnya/Rakdos)
Combinations Without Black 7. :symwu:/:symgr: (Azorius/Gruul) 8. :symgw:/:symru: (Selesnya/Izzet) 9. :symwr:/:symug: (Boros/Simic)
Combinations Without Red 10. :symuw:/:symgb: (Azorius/Golgari) 11. :symbw:/:symug: (Orzhov/Simic) 12. :symgw:/:symbu: (Selesnya/Dimir)
Combinations Without Green 13. :symwu:/:symrb: (Azorius/Rakdos) 14. :symbw:/:symru: (Orzhov/Izzet) 15. :symwr:/:symbu: (Boros/Dimir)
I'd expect these cards to have hybrid mana on each side, meaning you could use both sides of the :symwr:/:symbu: split card in :symru:, :symrb:, :symwu:, or decks, but not or decks.
That would have the interesting property that, given a split card, neither color combination represented on a side could effectively use both sides, but four other guilds would be able to use both sides! Thus, in terms of what decks it would work best in, the :symwr:/:symbu: card would not actually be a Boros/Dimir card, but an Izzet/Rakdos/Azorius/Orzhov card!
If the cards were not hybrid, but pure gold, then you would likely only be able to use a single side in a given deck. For example, a :symr::symw:/:symu::symb: would let you play the first side in decks only, and the second side in decks only, and you would only be able to play both sides in a deck with access to all four of those colors. That would probably defeat the purpose of making it a split card in the first place.
I was going to say the same thing (but not as detailed!). I doubt they would to split costs that could be paid with the same mana, so this theory seems really strong.
I don't think anyone on this site would vote "negative" on that poll. We are reading the "rumor mill." I think it's pretty obvious how we feel about them.
They may have a or on them as well, but I'm not sure about that.
Wouldn't it be more realistic (and more in-flavor for this block) to have each creature cost 1AB, where A and B are guild mana symbols? This would allow for a "four-color" card while still making sense and being actually castable. For example:
According to that Homelands is already the 3rd set of Ice Age Block
They called it a "block" years after those sets came out, but Mirage was really the first block. They grouped those three together later. Apparently WotC hates Homelands as much as we do.
I'm going to go out on a limb and speculate this could be an(the first) MTGO-only set. Build up interest with the other online releases, then pop out the first exclusive MTGO set. I always wondered why they hadn't attempted unique online-only promo cards at the very least. This would also explain any involvement from Alan Comer.
MTGO has redemption features for full sets. I don't think it's possible for this to be MTGO only.
The cards can't affect snow covered lands because no snow covered lands will not be legal in Extended or Standard, and they aren't online either.
However, cantrips, pitch cards, and gold cards are all awesome, so this is great. If only they would use the old card face : (

You know, I've heard that one before...

Mirage isn't online only, and it's out of print anyway.
This will be in-print, and legal in tournaments. There's no way they won't make this a real set.
