The changes included in this update are, roughly in descending order of the quantity of card swaps the change created:

• Change white's token to the Soldier, which allowed me to switch Ajani Goldmane for the significantly more powerful Elspeth, Sun's Champion and also get rid of the only unique token in the cube. I think this change brings White's general power level up somewhat to be more in-line with the rest of the cube.
• Remove Thopter and Servo token producers
• Swapping out a handful cards that were extreme power-outliers on both ends, notably Shivan Dragon, Serra Angel, and Bring to Light on the low end and Rancor and Umezawa's Jitte on the high end.
• Minor reduction in the density of broadly applicable, cheap removal by exchanging for more narrow or more color-intensive options
• Give Blue a distinct creature token with the Faerie.
