The market went that way because it had been two weeks since any news relating to characters had been announced. That
meant that fewer people were buying packs. Now that some CRs and some new characters are out, the prices have fallen a
little bit more, because people bought heaps more packs to try and get hold of the new cards and the ones that are going out.
That means more spares enter the market. Increased supply, similiar demand, lower prices.
