Trying to make a Poor Man's Cube

[poketo]

I've always wanted to get a cube since I've heard of it, but I don't have the money to grab all the pieces of some major decks to draft into. I'm thinking of making a Commons/light Uncommons draft to just keep things interesting using as much as I can from recent sets.

Archetypes I'm thinking on allowing are:
WW Lifegain (Soul Sisters, and redirecting the damage)
U Counterspells
B Death
R Burn
G Something

WU Fliers
UB Control
BR Aggro
RG Sacrifices
GW Power ups

and other things. I've have a list I'll upload piece by peice, and I want to know what people think would be good cards to grab like removal and creatures. I've never done one before and it should be a nice trial before I try grabbing higher priced cards.

EDIT: Their curves and creature counts are not equal yet.

I made my cube commons and uncommons because it just didn't feel worth chasing money cards for it.

Now, magic question. What is the size of your cube and do you allow multiple copies, since I've seen people do that and make their sizes larger than normal.

I'm probably just going to go with a 360 until I find a good amount to bump to 450 or higher. I'm am not quite sure about if I am going to have it double up on cards (maybe a thing I'll have to do).
BTW I have the list ready to post of what I've slid in so far, and balance is something I'll have to focus on soon enough.
