4 rulings from Wizards of the Coast
- 5 October 2018Creature cards with other types, such as artifact creature cards, count for undergrowth abilities.
- 5 October 2018Because tokens aren't cards, they never count for undergrowth abilities.
- 5 October 2018If there are no creature cards in your graveyard, the target creature just gains menace until end of turn.
- 5 October 2018The value of X is determined only as the undergrowth ability resolves. If the number of creature cards in your graveyard changes later in the turn, the target creature is unaffected.
