I put my Omarthis deck from last year back together, then I edited the crap out of it. The old deck was based on the "Eldrazi Unbound" precon, but this version departed from that in favor of squeezing more value out of Omarthis. Also, I included some new cards that weren't available back when I first built the old version. This version should be better. Let's manifest.
