This is a kind of post that I enjoyed a lot in /r/mtgcube in reddit. If you want to give a draft to my cube (I have a brief description in its overview about its archetypes and intended strategies), leave a link to yours and I’ll give it a draft too.
I also have a peasant cube in case you prefer it.
It’s kind of a pity that the draft got complicated, because the deck was looking very nice. I’d not try to go into 3 colors without any fixing for white. I’d go so far as to include Jubilant Skybonder, Tibalt, and the hypothetical Young Pyro into the deck just to avoid white altogether. Even if you went with that splash, having so many white sources would certainly be detrimental.
Do you have any cube to draft?
Currently I have very outdated cube Yang Tercecer, Kubik, if you wish so choose. Not every color pair is supported.
I drafted this UW tempo deck. I started picking some good white cards, but then I found Stormchaser Drake and decided to build around it. I may have ended up too threat-light, specially at the 2 cmc spot, but I also got some other powerful 3 and 4 drops, and a decent top end.
