MTGA Multicolor Cube

This cube is made entirely from cards that are available on MTG Arena - so that after drafting it is possible to export into arena and play each other. The theme is multicolor because those cards are just fun! The cube includes multicolor, colorless and lands.

The major/minor themes for each color pairs:
UW - flying
BW - lifegain
UB - graveyard
UR - instants/sorceries
BR - menace
GB - graveyard, deathtouch
RG - trample
RW - mentor
GW - tokens, vigilance
UG - 1/1 counters, proliferate

Notable exclusions from the cube:

1. stonecoil serpent - too powerful for the format
2. chromatic lantern and other "add mana of any color" - trivializes mana fixing, push 5c goodstuff too much
