Probably they will be tradable in the near future.
According to the website of Magic Dice, "MAGIC tokens will be created as SMTs(Smart Media Tokens) when SMTs become available on Steem. Until then, the tokens are only getting distributed, but aren't transferrable or tradable. The dividend payout will start before the MAGIC Tokens are created as SMTs, in February 2019.
