原文Colleen Wing's last ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack without resolving.
原文Colleen Wing's last ability triggers when you cast a spell that has multiple targets, as long as at least one of those targets is a creature you control. It doesn't trigger multiple times if you cast a spell that targets a creature you control multiple times or that targets multiple creatures you control.
