Mid-power cube mostly based around loose synergy and cards I like.

Broad themes from most to least aggressive -
Jund aggro/aristocrats
Naya tokens/populate
Bant tempo/heroic
Grixis midrange/2-for-1s
Esper control/miracles

Decks generally are one colour pair (most likely allied) splashing the third in the shard. Colours look imbalanced because cubecobra calls Pride Sovereign and Garruk GW and GB.
