Question! Why? In most cubes, people support the 10 2 colour combinations, is there a difference with this now? How has it changed things?
I only support the ally color pairs, but according to my colorshifted wheel. So UB and UR are supported, for example, but not WU and GU. I switched to this system for a few reasons:
1. It's novel. My cube plays differently from the other cubes existing in our playgroup.
2. I wanted to more heavily support multicolor decks, but if you support all ten pairs, you run into certain problems. It's why WotC didn't put all ten guilds in the same set in the Ravnica blocks.
3. If you support all ten color pairs, a few of the drafters will end up in a color combination that no one else plays, meaning they get to pick up all the good multicolor cards in their guild basically for free, even wheeling them. While you could argue that that's a fine reward for reading the draft and picking the right colors, I wanted a little more tension between the drafters.
4. Restricting yourself to only five supported color pairs means the fixing is way better than it is in regular cubes, simply because there's more lands per guild. This means every player should be able to pick up some fixers, provided they prioritize them.
5. I wanted to support three color cards as well. Cards like
Nicol Bolas and
Cruel Ultimatum are fan favorites, that really have no place in a regular cube. By supporting only five two color combinations, I can also support the three color combinations that can be formed by pairing each of the guilds with each other.
5b. To further support three color decks, I have an additional rule that you get a triland with each three color cards. So, for example, if you pick up
Cruel Ultimatum, you also get a
Crumbling Necropolis for free after the draft, which you may use in deck construction. This has been a tremendous good way to promote three color decks (and even the occasional four color deck).
Last but not least, I have to give credits to Jason for coming up with the idea.
