I added some faster ramp so we can establish our board quicker (Azorius Signet), added all the best remaining spells we can cast from our graveyard (Beacon Bolt), added more ways to recur our graveyard (Recoup), tossed in an auto-include tutor (Quiet Speculation), and opted to go for a Token subtheme (Saheeli, Sublime Artificer) which can help protect us early/midgame and can eventually turn into a finisher once we move lategame (Rally the Peasants)
Watch for it to continue to see play in Amethyst/Steel and to make appearances in Amethyst/Ruby
Having more total lands means we're less likely to have games where we are mana screwed
The quantity of cards you have is important, however, which makes casting Life from the Loam as often as possible very important
Two have been added to the previous six
Nasty winning condition, great to recur over and over again, and machine of love
