Creature â Merfolk Scout
When Forerunner of the Heralds enters the battlefield, you may search your library for a Merfolk card, reveal it, then shuffle your library and put that card on top of it.
Whenever another Merfolk enters the battlefield under your control, put a +1/+1 counter on Forerunner of the Heralds.
If an effect refers to a â€œ[subtype] spellâ€ or â€œ[subtype] card,â€ it refers only to a spell or card that has that subtype. For example, March of the Drowned is a card that benefits Pirates and features Pirates in its illustration, but it isnâ€™t a Pirate card.
