This is a cube designed to support two color archetypes that are able to support mixing and high synergy, I went with four colors because in my other 5 color winston cube I very often end up in 3 or more color decks, and I wanted to test the possibility of being able to build 2 color decks.
Archetypes:
WU = Blink
WR = Aggro/Tokens
WG = Tokens
UR = Spellslinger
UG = Big Spells
RG = Stompy
