From the Compendium of Rathe release notes

Limbs of Lignum Vitae’s first ability generates a continuous effect that always checks the number of Earth cards in your banished zone. If this is defending with 3 Earth cards in your banished zone, and then you banish an Earth card, this gets +1. If you then remove an Earth card from your banished zone, it loses the +1.
Earth cards that are face-down in your banished zone do not count towards Earth cards in your banished zone.
