Nothing to crazy here.
Trying out a few of the new Sword cycle (removing Light/Shadow will conveniently make each color represented equally). Removing some middling vehicles and adding other equipment that's well-received in the cube community.
Since I'm adding the remainder of the Talisman cycle, I'm removing some other mana rocks.
Things to look out for in the future will be how well represented the colorless mana production is for some of the colorless-required mana costs in the cube, and if I want to add any more support at the high-end for Eldrazi-style creatures (reanimator, Selvala's Stampede, green ramp, etc.). I might like Scuttling Doom Engine back in considering it's fun with Goblin Welder.
