I think Japanese attention gives us an even higher chance of seeing physical TCG cards. Japan had has so many successful TCG's pokemon, yugioh, was MTG Japanese? I don't think it was... but yeah! I'm still for this idea of physical cards and I don't think it overcomplicates things at all. Can you explain how it does?
Because now you have to deal with printing, packaging, manufacturing, more advertising etc.
Pokemon, Yugioh, FoW, MtG are physical games first and foremost whose dynamics translate well to digital.
Spells of Genesis is a digital game first and foremost that does not translate well to physical.
I don't see much point in spending money on producing physical cards that have no use at all outside of the digital game other than to "hold".
EDS doesn't need to do it though... they can license the cards to a company that does cards...
