Is the game really not going to let the cleric not heal himself when he's the only one playing?
From this wording I think that healing strike cannot be used on himself. It sucks but thats the way it's written and make Solo play with these cards useless. Have a look at these italic scripts and let me know what you think.
My mind not only wanders, sometimes it leaves completely.
The Cleric cannot heal himself with the Healing Strike.
I am convinced that the Cleric can indeed heal himself with Healing Strike. For me it comes down to the wording "other Hero" such as exists in the Cleric's Aid ability and the Hallowed Advance power.If it says "Hero" it includes the acting Hero; if it says "other Hero" it specifically excludes the acting Hero.As already mentioned, the italics are flavor text and not mechanical text. Although they might be considered when discussing the intent of the designer they are not part of rules. Further, if you use the logic that the flavor text for Healing Strike only mentions companions then the Cleric would not be able to use Healing Word on himself either.
