Vigilance

As Anointed Peacekeeper enters the battlefield, look at an opponent's hand, then choose any card name.

Spells your opponents cast with the chosen name cost more to cast.

Activated abilities of sources with the chosen name cost more to activate unless they're mana abilities.

At the beginning of your upkeep, the player with the lowest life total gains control of Loxodon Peacekeeper. If two or more players are tied for lowest life total, you choose one of them, and that player gains control of Loxodon Peacekeeper.
