Alakazam Magic is one of the longest established magic companies in the United Kingdom. Bicycle Dr Jekyll Playing Cards and Bicycle Mr Hyde Playing Cards is the new set of playing cards produced by Alakazam Magic in 2013. These two decks are the set because they are connected and have the common general theme – Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson. So they supplement each other and pretend to be used in combination.
