Can I include Riveteers Overlook (or other similar cards) in a Commander deck with a red and black Commander? I know the rules regarding color identity, but Riveteers Overlook specifically names Mountain, Swamp, and Forest land types:
When Riveteers Overlook enters the battlefield, sacrifice it. When you do, search your library for a basic Swamp, Mountain, or Forest card, then put it onto the battlefield tapped, then shuffle and you gain 1 life.
Does this include the associated colors in the card's color identity, or can I use this to fetch a Swamp or Mountain and ignore the Forest keyword?
I know that this rule exists:
903.5d A card with a basic land type may be included in a Commander deck only if each color of mana it could produce is included in the commander’s color identity.
But as the card does not have the basic land type I did not know if this rule affected it.
