This cube is designed to be drafted by 4-8 players.
Each player starts the game with an emblem that has "4: Proliferate. Active this ability only any time you could cast a sorcery and only once each turn."

The Thriving land cycle and Baldur's Gates cycle have been altered for this cube, and I'll use Thriving Meadow as an example, with it gaining the plains land type and new text reading: "Thriving Meadow enters the battlefield tapped. When it does, choose Island, Swamp, Mountain or Forest. Put a counter of the chosen type on Thriving Meadow".
The result of this is exactly the same effect for the land played by itself, but it does mean it starts interacting with counter movers and destroyers.

This cube also contains the card Garbage Elemental and for it some calls needed to be made around what is and isn't a "figure" in the artwork.
Navigating to this link will show you the current standing of each creature in the cube based on the artwork we're using. This link for the tokens.

The tokens that are used in this cube can be found here.
