I beat one in the late game with a crappy galalrond priest deck I did play the 8/8 card that copies cards used. So I got a free embiggen and a drew 3 cards with nourish. Then I got the 1 cost discover a minion spell from opponents deck off the 3/5 dragon. I found a 9/6 rush divine shield dragon :]
Update. Beat 3 more embiggen druids today with my memeish highlander galakrond priest. I think I am getting a bit lucky but it’s nice to have a deck I can somewhat consistently face since most of them rip galak priest apart.
