Trying to build a cube with unusual archetypes.
my current ideas:

Selesnya - Sacrificing for fun and value
Rakdos - sagas and counter manipulation
Golgari - scourges of the sky
Izzet - +1/+1 counters
Boros - reanimator
Simic - tribal tribal
Dimir - Ramp and stomp
Gruul - control
Orzhov - spellslinger
Azorius - burn
