Can't say I really understand the desire for japanese cards either, I like reading my cards. Anyway, non-foil Japanese Mother of Runes shouldn't be too hard to find, but if you want foil I guess you need to look a bit around.


Slightly on topic:
I might be testing this deck for a local legacy-tournament on the 19th of August, but haven't really decided what deck to run yet. There hasn't been legacy here for about a year, so I have no idea what the meta will look like. Will give you the results if I do decide to run UW Tempo (alternatives are Zoo, Enchantress or UGr Thresh).
