Old-Growth Dryads
{G}
Creature — Dryad
Oracle Text
When this creature enters, each opponent may search their library for a basic land card, put it onto the battlefield tapped, then shuffle.
Watch Out
ETB trigger, not a cast triggerRules Note
This card's ability triggers when it enters the battlefield, not when it's cast. Effects that double ETB triggers (like Panharmonicon) work here. Countering the spell prevents the creature from entering, so the ETB won't fire.
