STILL WORK IN PROGRESS

This cube is played using the following special rules:
You may have lands enter the battlefield tapped, with an ancient counter on it. (You can do this also with lands that would normally enter tapped).

At the beginning of your draw step, tap each land with an ancient counter on it for mana (if possible). Rather than adding mana, you draw a card for each mana that would have been produced this way. You can not tap these lands for mana any other way. (Other abilities, including mana abilities) work as normal.

You start the game with 2 basic lands of your choice (those lands have no ancient counters on them). You choose which lands before you draw your starting hand. These lands are phased out until the start of your first turn.
