Question

There was a recent question that made me realize we’d drawn some conclusions without official input (that I can find). Do costs require valid targets, or only effects? In particular, if Go For Champions is in effect, can I use Clarity of Purpose if I’m a Champion, or similarly can I use the Ms Marvel (Nova’s ally) ability. These abilities both have you deal damage to the character, which is allowed even when they don’t take it (such as if they are tough). But they are not valid targets to deal damage to. It seems like this means that a character that cannot take damage cannot be dealt damage (i.e. is not a valid target for it), but I’m not clear on if ‘target’ is a specific term that only refers to ‘effects’, and not cost resolutions.
