Choose target creature. Mill four cards, then put a +1/+1 counter on that creature for each creature card milled this way.
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.
