Wow, interesting. I just thought my black dudes (other than Harpies) were bad so I never played them.
Match one I went with the full-on Jund with all the double colored cards. I lost a close match one after we split the first two (G1 I flooded, G2 he screwed). G3 I Critically misplayed playing Cyclops at 9 mana when I could have waited a turn and played and monstrosified it in the same turn. It ate a lightning strike (and I knew he had this and fated conflag). Drew nothing but lands after that.
I decided it was too janky and cut all the the black except for gild and feast of dreams. I won match 2 pretty easily but got destroyed by UW heroic in match 3. I did get into a funny situation in M2G2 with both Ember Swallower, Hammer, and like 7 lands + Market Festival in a big board stall. I ended up monstrifying ember because of his
Thassa's Ire and he conceded before I got to make any enchantment golems for
Eidolon of Blossoms I basically ran 16 lands with 2 fonts, nickel, and Market Festival. I mulliganed a bit more than usual.
Market festival was pretty good with monstrosity and 3 colors.
