I decided that this guy was being a leader to that other guy in the art. So I made that the focus rather than on whatever that thing is in the background (my words are so descriptive!). So, the ability here is him leading someone else with his stats. The "another target creature" makes him differ from Wyluli Wolf (and acceptable at uncommon).
Because the focus is not on him being awesome (an Elite), I decided on the "Captain" word to evoke the him-being-helpful-to-others aspect.
