The Baldur's Gate release opened up a ton of new space, and there was so much Dragon support that we shifted the RG archetype to Dragon tribal!
We heavily redid the 3-color commander roster; now each 2-color archetype is represented, and the overall power level is lower. We want to minimize 3 color "goodstuff" piles. Cutting 10 duals also helps for this.
A handfull of underpowered and overpowered cards are also getting cut!
