I think Horton could work as a jouster with BB-8. He's got high enough PS that you can react to what's going on. Y wings have a decent slow dial...they just aren't fast. That comes in at 33. Conversely, you could knock BB-8 and put EU on him. That's 35...which for some reason feels too many points to me compared to 33 :-(
In addition to being chepaer, BB-8 also gives you some protection against getting blocked. Not that Horton is terribly action-needy.
Either one, though, I think, in competent hands, should allow Horton to get to where he needs to be.
With only a 1 and 2 straight as green... He'll still be very easy to block, even with BB-8.
