I tweaked the quarterly update cadence to align with roughly when CubeCon lists must be submitted.

An interesting thing about this update is that Time Vault made the cut. Sadly, the only ways of untapping the vault in the cube are Pestermite and Zealous Conscripts. Bad card inclusions will happen from time to time when we are aggreatating data. In cases like this the vault is part of a 2 card combo where vault itself is a unique effect only printed on a single card while the untap effect can be a myriad of things including Voltaic Key, Manifold Key, Mirage Mirror, Scheming Fence and Kiora, Behemoth Beckoner to name a few. Because there are so many pairings with vault, they tend to cancel each-other out when doing frequency analysis and none of the other halves of the vault combo make it into the cube. So, cube curators are putting Time Vault into their cubes, but the untap effects are varied enough that they get washed out of the analysis. I'll keep the vault in this cube update, but I ran the algorithm with a blacklist consisting solely of Time Vault and based on that will be playing Lodestone Golem in it's place.

Outside of that change, I'm happy to see both Lightning Helix and Bloodghast go as they were too narrow.
