Strength of Four Seasons (Yellow)

This has a static ability which constantly checks the number of Earth cards in your banished zone. If this is attacking with 3 Earth cards in your banished zone, and then you banish an Earth card, this gets +4. If you then remove an Earth card from your banished zone, it loses the +4.

Earth cards that are face-down in your banished zone do not count towards Earth cards in your banished zone.
