The latest changes had two main themes:

1. Add more lands so that we reach 90 lands when playing the base cube with an extension. This means having at least 25ish lands in this cube extension.

2. Improve the aristocrats archetype in the Vintage extension which meant switching cards between Legacy and Vintage extension so that there is a better balance.

While 2 resulted more or less in removing cards from the Vintage extension to make room for cards from the this Legacy extension for the latter it meant bringing back older cards that I already removed like Custodi Lich.

1 actually resulted in cards leaving the base cube mainly in the direction of the Legacy extension cube that forced out cards in this extension.
