Ezuri, Stalker of Spheres
{2}{G}{U}
Legendary Creature — Phyrexian Elf Warrior
Oracle Text
When Ezuri enters, you may pay {3}. If you do, proliferate twice.
Whenever you proliferate, draw a card.
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.
