If they keep all the OG "dream" cards this is solid, because it means you get 0 mana "return a minion to it's owners hand" instantly. I'm betting they will change it to only target enemy minions, otherwise you could get Infinite Ysera.
We changed some of the Dream cards, Dream itself targets enemy minions now and is 1 mana.
