Death Star II (2000) - This set was the second to focus on the end of Return of the Jedi and along with Endor forms a stand-alone environment, in which all of the cards from those two expansions can be played independently of the other sets. This was also the first set to feature ultra-rare cards (Luke Skywalker, Jedi Knight and Emperor Palpatine). The inclusion of these two very powerful and iconic characters, in addition to many useful supplementary cards, coupled with general praise for its elegant design, has given the set lasting appeal and led to it being, as of 2009, one of the more expensive sets to purchase. This set, and all after it, were sold in 11-card packs for a retail price of US$3.29.
