Rulings

A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost. — Devoid doesn't affect the color identity of the card for the purposes of the Commander variant. For example, while Abstruse Appropriation is colorless because it has devoid, its color identity is still white and black, and it can't be included in a Commander deck where the commander's color identity doesn't include both white and black. — Devoid works in all zones, not just on the battlefield. — If a card loses devoid, it will still be colorless. This is because effects that change an object's color (like the one created by devoid) are considered before the object loses devoid. — Other cards and abilities can give a card with devoid a color. If that happens, it's just the new color, not that color and colorless. — You don't have to reveal the card even if it's a creature card. You may leave it on top of your library or put it into your graveyard. — A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land. — A landfall ability triggers whenever a land you control enters for any reason. It triggers whenever you play a land, as well as whenever a spell or ability puts a land onto the battlefield under your control. — Whenever a land you control enters, each landfall ability of the permanents you control will trigger. You can put them   on the stack in any order. The last ability you put on the stack will be the first one to resolve (As a result, you can have those abilities resolve in the order of your choosing.).
