Domain — Creatures can’t attack you unless their controller pays for each creature they control that’s attacking you, where X is the number of basic land types among lands you control.
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.

Unless some effect explicitly says otherwise, a creature that can't attack you can still attack a planeswalker you control.

In the Two-Headed Giant format, you still only have to pay once per creature.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
