Multi-colour Cube

The core of the cube is (loosely) based on the guilds of Ravnica to keep the main focus on multi-Colour, but upgraded with cards from other sets to maximize their power, options and/or Syngergy.

Some guilds have been adjusted more than others, by adding more cards outside of the sets and/or by creating another theme for the "guild".

Also weaved in the Theros Gods, to give every Guild a boost/bomb/"Leader". (some with a bigger succes than others, but then again wanted to keep up the complete cycle of Gods)

Themes are connected with the other guilds and/or mono colors. So if needed you could easily play well rounded 3-colored decks. For example: Playing W/B/R has a synergy with aristocrat, graveyard recursion and some life gain/steal (reactions). In other words; Orzov, Boros and Rakdos. Depeding on drafted cards you theme could be more Aristocrat with equipment or Vampire Aristocrat or something else.

Although 2-color is also possible and by creating more weight of the number of mono-colour cards it should be easy enough.

Main themes:
Azorius: Artifact, Control, Flying, Flicker.
Boros: Equipment, Combat tricks
Dimir: Unblockable/Evasion, Control, Discard,
Golgari: Graveyard recursion and Life steal/Gain
