Vitality Hunter

Text:

Lifelink
: Monstrosity X. (If this creature isn't monstrous, put X +1/+1 counters on it and it becomes monstrous.)
When Vitality Hunter becomes monstrous, put a lifelink counter on each of up to X target creatures.

Rulings:

• 4/17/2020 Once a creature becomes monstrous, it can’t become monstrous again. If the creature is already monstrous when the monstrosity ability resolves, nothing happens.
• 4/17/2020 Monstrous isn’t an ability that a creature has. It’s just something true about that creature. If the creature stops being a creature, loses its abilities, or loses its +1/+1 counters, it will continue to be monstrous.
