From De Other Side

Since there is no way to cheat this out that I can think of, this feels pretty bad to me. The big minions shaman has got from this expansion interact very well with this card, but as a 10 mana play it feels pretty lacking and inconsistent, since you can’t even choose which minions to target. Notable combos: the 9 mana undead neutral minion which has deathrattle: draw and summon a copy with taunt of another undead minion; the 8 mana 3/8 taunt undead minion for shaman which lifesteals and deals 3 damage on death (it also has reborn); Neptulon, since it will summon the 4/2 arms which won’t die at the end of the turn and that can be followed up by the Neptulon you have in hand, making it twice as strong; Grugg summons 4 2/2 with taunt which also don’t die at the end of the turn; Denathrius heals you for 10 and all those minions dying infuses the “real” Denathrius in your hand.
So, I’m not saying that the combos aren’t there: they are easy to make and relatively powerful. The issue is the mana cost: if this costed 8 or 9 mana, then it would be something to be reckoned with, but at 10 mana I fear that it’s going to be way too slow to see actual play.
