A synergy-heavy cube with lower individual power levels, made up of some of my favorite cards and archetypes from over the years.

Relevant Arcana:
-Arcbound Bruiser is a Golem.
-Planar Guide is a Human
-Subterranean Spirit is a Spirit.

The archetypes are:
WU: Blink
UB: Hexproof Cipher
BR: Vampires
RG: Phoenix mass damage
GW: Tokens
WB: Life Drain / Creature Sac
UR: Artifacts / Artifact Sac
BG: Spirits / Self-Mill
RW: Fliers
GU: Proliferate

And of course, more are possible.
