Vadmir, New Blood (Promo Pack) [Outlaws of Thunder Junction Promos]

Whenever you commit a crime, put a +1/+1 counter on Vadmir, New Blood. This ability triggers only once each turn. (Targeting opponents, anything they control, and/or cards in their graveyards is a crime.)

As long as Vadmir has four or more +1/+1 counters on it, it has menace and lifelink.
