Selesnya Pauper/Cheap

Pauper in commons only. Rancor is not a common.

depending on what you are wanting the deck to do, there are a lot of good cards to be found. these are some of the cars i use in EDH decks of mine.. one idea is use the Utopia tree,Darksteel Ingot, and Birds of Paradise instead of the keyrunes to give you the extra mana, Elvish Piper lets you get big creatures on the field for 1 mana cost, i put in a variety of cards ideas here cause i wasn't sure if you were going for a populate theme, a big creature in your face type or a combo of... but with the cards you ahve and this list you should be able to have a lot of fun tinkering and to tweek your deck to where you are happy with it ... hope this helps some:
