barnes is a really awesome and fun card, that really hasn't seen the light of day in a long time. But i feel like he really only has 2 good targets, Xhilag of the Abyss and Pit Commander. the rest of the minions are pretty bad. Maybe when he was 4 mana that is alright, but I think at 5 mana he is so garbage if you don't highroll. 

In one of my deathrattle druid decks, i really wanted to put barnes in because I also think he is a really fun card. He had a few bad targets, so I slotted in Ambassador Faelin to hopefully increase the amount of good targets. ambassador also synergizes with Topple the Idol

Agree on a most parts, Barnes is good as card that can fill some board when you don't have Sigil of Reckoning and Caria Felsoul. Ambassador great addition if you need more recources for the deck.
