I'm not sure where you're going with this. But let me give you an example.
Yesterday, I tried to draft UB control. I got some good processors (p1p1
Wasteland Strangler and two
Ulamog's Nullifiers), but no removal. I also got two
Skyrider Elf and
Exert Influence. So I switched to full control, using counterspells to exile things, some awaken for tempo/value, and the black allies for some life gain. The deck looked a mess, it had at least three themes going, mana base was 7/7/2/1 UBGW and an
Evolving Wilds, but it played surprisingly well. 2/1, with a really close loss to another UB deck.
There are a
Rising Miasma,
Bone Splinters,
Blighted Fen,
Sheer Drop,
Smite the Monstrous and
Desolation Twin in the sideboard. I boarded out the six drop for Smite a few times.
Point is, don't go overboard for synergy. I only started drafting the black allies in pack three, when I finally noticed that Skyrider and
Halimar Tidecaller are also Allies. The Nullifiers and the counters and Infiltrator work by themselves, no need to pass them if they fir your deck without ingest/process.
Oh, and did I say that I will be forcing blue in this set if at all possible? It's just so versatile and fun. Well, not for opponents who get things countered, but I really enjoy it so far.
