don()shinobi, maybe they just like to tease us? I mean, think about it this way: the Hanzo tin got announced with Rescue Rabbit (a very playable card) and Shock Master (a slightly-less playable card). Why bother bringing Shock Master up? unless they're hinting that the best is yet to come.
Plat-Cofa interpreted the rest of the tins similarly; I'll need to ask him about his findings. (Or you could ask him, whatever works.)
