A really nice deck you've put together here. I'm running a similar, politics-based Zedruu-deck aswell ( Zedruu, Enlightened Master), but i fear the budgetlevel is slightly different... so my props to you, for you seemingly have managed to build an absolutely playable budget Zedruu-deck with some very cool and unique strategies :) While you do have a very low CMC, i'd still probably run more lands, something between 35 to 37, as we're playing Jeskai and there aren't to many ways to ramp, so we need to rely on our landdrops... Some budget-additions might be: Nimbus Maze , Prairie Stream , Sejiri Refuge , Wind-Scarred Crag and the other life-lands. I'm also recommending Rainbow Vale as a very political card, that might be usefull by forging alliances... .

Whatsoever i'm pretty impressed with your decklist, upvote from me :)

Thanks for the input NetholonTheArchmage! I've been trying to tack more towards low-cost ramp rather than lands since lands become a liability once Zedruu's card draw gets rolling - however, I agree that a few more lands would probably help at the start. Rainbow Vale in particular is a great suggestion since it's actively political and self-donating. Prairie Stream also looks like solid value for the price. The others I'm not sold on since they're a bit slow.

I'm still actively tweaking this deck; the description is out-of-date and missing some key info, so once I get a chance to playtest the latest changes I'll be giving it an overhaul.
