This is the Onyx Bishop HS Priest Card that will be released as part of the new adventure coming in August – One Night in Karazhan.
The card reads: Battlecry: Summon a friendly minion that died this game.
This is similar to Rssurect, although it’s more expensive and comes with a 3/4 body. It’s not exactly what Priest was lacking, but it’s a decent card and will see some play I’m sure.
