I'm going to hold off a while longer, there's a lot of Untamed packs left!
And the price is coming down, and I don't even play Fire!
Also, if Yodin is overpowered, what are Water and Earth, let alone Dragon going to look like?!?
I'm expecting a new ability with at least one of those next summoners.
Yes, you are right, it is impossible to predict, the price of the cards changes as new cards emerge, but I am anxious and wanted to use it soon :D
