River Herald Guide
Creature — Merfolk Scout
Vigilance
When River Herald Guide enters the battlefield, it explores. (To have it explore, reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a !/! counter on that creature, then put the card back or put it into your graveyard.)
