Rinoceronte Dorsonodoso

Gnarlback Rhino's last ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

Gnarlback Rhino's last ability triggers when you cast a spell that has multiple targets as long as at least one of those targets is Gnarlback Rhino. It doesn't trigger multiple times if you cast a spell that targets Gnarlback Rhino multiple times.
