## Official Rulings
- *(2016-04-08)* You may reveal any land card with either or both of the appropriate subtypes. It doesn't have to be a basic land. For example, you could reveal Prairie Stream from the Battle for Zendikar set to satisfy the ability of Choked Estuary.
- *(2016-04-08)* Lands don't have a subtype just because they can produce mana of the corresponding color. Choked Estuary itself is neither an Island nor a Swamp, even though it produces blue and black mana, so you can't reveal one to satisfy the ability of another.
- *(2016-04-08)* If an effect instructs you to put Choked Estuary onto the battlefield tapped, it will still enter the battlefield tapped even if you reveal a land card from your hand.
- *(2016-04-08)* If an Island or Swamp is entering the battlefield from your hand at the same time as Choked Estuary, you may reveal the other land to have Choked Estuary enter untapped.
