Rulings:

• 1/22/2016 Use the number of creature cards in your graveyard as the ability resolves to determine the value of X. Seed Guardian will count toward this number as long as it’s still in your graveyard at that time.
• 1/22/2016 Once the Elemental is created, the number of creature cards in your graveyard changing won’t cause the Elemental’s power or toughness to change.
