Constricting Sliver
{5}{W}
Creature — Sliver
Oracle Text
Sliver creatures you control have "When this creature enters, you may exile target creature an opponent controls until this creature leaves the battlefield."
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.
