The 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.

Necrotic Wound’s replacement effect will exile the target creature if it would die this turn for any reason, not just immediately after Necrotic Wound resolves.
