That winning Eldrazi list is SICK! The white splash for Thalia and friends is amazing. No Workshops puts this list squarely in the "budget" category for me (even though it is powered) it looks like it could be run competitively with Sol Ring, Mana crypt and Mana Vault. If I had to play sanctioned Vintage tomorrow this would be what I would try to run.
Thanks for posting!
Very cool deck. I don't know a lot of those cards, but would love to find a Legend creature that has a "come into play" effect that would synergize with the MD Karakas.
