Last defence

Vigilance, reach, lifelink, double strike, hexproof, indestructible
If 'Undyne the undying' has been on the battlefield for more than three turns, exile it.
You'll destroy them all, won't you?
Monsters... Humans... Everyone...
Everyone's hopes. Everyone's dreams. Vanquished in an instant.
But I WON'T let you do that.
