The "end of your turn" part kills it, there's no way the tokens will survive for you to use them, not when you're sacrificing this much tempo. It synergizes well with Steward of Darkshire, but that's about it.
Maybe if it summoned the token at the end of your opponent's turn, then you could actually reliably get a buff target.
I guess it's pretty bad, but I might try it in divine shield aggresive paladin with Steward of Darkshire, because with it this needs not 1, but 2 AOE's. Still seems pretty slow for that deck, but who knows.
