Watcher of the Wayside [Tarkir: Dragonstorm]

When this creature enters, target player mills two cards. You gain 2 life. (To mill two cards, a player puts the top two cards of their library into their graveyard.) Against dragonlords, khans, and Ugin himself, the golem survived. Original purpose forgotten, it awaits orders that will never come, from a world that has moved on without it.
