How do you get Medals for the trade shop?

Purchasing stuff in shop. Nutaku fooled a lot of cashers because this was implemented at mid of event (again?), so people who invested Nutaku gold on SEC or stuff at 1st phase was pwn3d (including me).

They should expand the time limit to offer that cards (i want Airu, is like $50 in purchased stuff), not rushing events as did the shitstorm on last medal campaign.

I have to agree with @chillinfar. This medal campaign is pretty asinine since most cashers probably spent a bunch of money at the beginning of the event to stock up on puddings and/or try to get special effect cards. Elite Guard depends pretty heavily on special effect cards since they directly affect your event SED and have no luck component, as is seen with Gambit.
