Today at the pre-release someone had a Phalanx Leader and they targetted it with an enchantment. In response I bounced it. They said "That's fine, I still get my 1/1 counters on my other creatures because he was targeted and the ability went on the stack.
Is this true as well if I were to counter the spell that targets the Phalanx leader? Targets are assigned when you cast not resolve the spell... so is heroic strong even against counter magic?
