I've been kicking around the idea of building a 5 color deck and could use some help with ideas as to what to do with it. Also, I would like to keep this deck to a fair budget (I'm currently limiting myself to $50 per month for MTG and have spent about half that amount for this month). Of course, the first obstacle to overcome with 5 colors is going to be mana. I was considering buying 4 copies of each of the 3 color lands from Shards of Alara and maybe 2-4 copies of City of Brass or 4 Birds of Paradise. The downside I can see to this idea is having almost all my lands enter the battlefield tapped. The other idea which I've heard for 5 colors is to run Green (for mana fixing) plus 2 other colors and include the 4th and 5th colors in very minor roles (I'm thinking just for the 5 color spells). The other thing I have to decide is what I'm going to do with 5 colors. I've thought about building a deck that uses Progenitus and have come up with 2 possible ways to be able to play it: Elvish Piper or Mirari's Wake. Of course, I think those cards run $10-$15 each so this may have to be a deck that I buy the cards split up over the course of a couple months. My second idea for the 5 color deck is Slivers (just because I know there is a pre-built 5 color sliver deck out there, but I prefer to use decks I built over pre-existing ones). I think from looking at sliver cards that the idea for this deck would be to take advantage of the abilities that my Slivers would gain as I put more out. So, those are my thoughts on this deck for now. I could use some other input on this idea as well as card suggestions.
