Rulings
- 2007-02-01:
In the Two-Headed Giant format, you still only have to pay once per creature.
- 2014-02-01:
Unless some effect explicitly says otherwise, a creature that can’t attack you can still attack a planeswalker you control.
- 2021-03-19:
Domain abilities count the number of basic land types among lands you control, not how many lands you control or how many of any type.
- 2021-03-19:
The basic land types are Plains, Island, Swamp, Mountain, and Forest. Land types other than basic land types (such as Desert) don’t contribute to domain abilities.
