Just wondering, is there a certain reason as to why they aren't able to be sold or trade?

Get banned in a acc>get a fake>Get shiais in the fake>get unbanned the acc that get banned>transfer the shiais.Thats like useless ban,and shiais is for peoples that diserve them,nots everyone that diserve them

one another note that you have this thread open will shiai tokens ever be taken out of the game?

Shiai tokens are prizes from GM events, designed so that you can get a 3D item prize when you redeem them.

We want the people to win the tourneys to redeem the prizes, making them transferable would mean it would just be, who has the tc to buy Shiai Tokens? - They get the items
