I am working on reworking the entirely of how my cube will be working. My goals with this rework is to have it focus around and enhance battles. To accomplish this I am intentionally making games smaller for longer, a lot of the cards especially low cost cards in the cube will either lower the amount of cards on the battlefield or hands or go neutral along with making card advantage much harder and more expensive and reducing snowballing effects and cards so games aren't dictated by a single card or curve out. It will be possible with smart play be able to have a true comeback instead of "I drew my I win card or sweeper".

Another thing I am trying to do is making battles be power outliers when they are flipped, the decision to ignore tempo and go for the battle will be the defining feature of the format.

This isn't a finalized list for the gold, just the start... I will be going back and editing this as I go along. All of the battles will be in as a 2-of so density and prevalence are high enough for a theme and the rest of the gold cards are meant to be synergistic with them (example Invasion of Kaladesh being paired with a UR artifact matters package).
