My bad about the Therapies. I'm used to seeing the prices for those I run. FNM CTs, they're a bit more spendy :laugh:.
The manabase is the most important part of the deck, by the way. Fetchlands (and specifically Catacombs) first, duals later. You'll want to aim at having 14 initial manasources for each colour you run, meaning you should have 14 cards that can get you green mana on T1 and 14 cards that can get you black mana on T1. Fetchlands should count to 1 for each colour.
As an example, currently I run this manabase for my Junk Fit list:
4
Verdant Catacombs4
Windswept Heath2
Marsh Flats1
Bayou1
Savannah1
Scrubland2
Forest2
Swamp2
Plains1
Phyrexian Tower1
Volrath's Stronghold
This puts me @14 for each colour.
