I take it those are your arguments for Zendikar being the next setting? I mean Zendikar does have Kraken, I remember that much.
"Argument" is a strong word. However, Zendikar does have many powerful things, lurking, in the deep. That give magical power to lackeys. Powers similar to those in the Subclass.
Okay you are starting to win me over to the possibility of an official Zendikar setting being a possibility.
