I might make some more, having more ideas for this stuff
about Snowflake Grandmaster that suspiciously resemble NG Hanzo:
Hanzo (technicly, in my mind) apears in Snow Flake Attraction's artwork touching an Ice counter (wich then posseses him and turns him to Snowflake Grandmaster)
and snow wyvern also has artwork story but thats for another card thats not here yet..

anyway, tell me if something is OP'd\UP'd (like maybe Magical Snow Flakes?)
