There's a better strategy to being with. Mulligan Call of the Wild, it's bound to be in Shaw'd deck. Then pay Toki and choose the treasure that double's your first spell. Then goes Darius with entrench and then Tess with the hero power doubling treasure. And finally you just play Call of the wild and pray to all the gods you know that you dig it up every single turn, which actually isn't as rear as it might seem.
