Enemy Color Focused Peasant Cube! Drafting and Feedback Requested!

Hey all,

Finally got around to uploading my cube again after giving it a rather large overhaul! I'd really appreciate anyone drafting it and letting me know their thoughts! If you have a cube you'd like me to draft, save your deck on CT and I'll have a look at yours as well!

As the title suggests this Peasant Cube focuses on interactions between the Enemy Colors:

-WB: Lifegain Synergy/Combo

-UG: Evasion Tempo

-RW: Token Aggro

-BG: Graveyard Midrange

-UR: Spells Control

The idea is that you can sometimes splash a third colors to add variety to these 5 base decks and be creative.

Cheers,

Muli

PS. In particular I'm not really sure what to do with the artifacts and colorless stuff. It was originally going to be more focused on in UR but I switched it around a bit. Any thoughts or suggestions here would be REALLY appreciated! Thanks!
