This is part of a series of "stocking stuffer" decks using mostly commons and uncommons along with relatively cheap rares for people looking to gift competitive starter-style decks to friends who haven't yet discovered the game. The decks don't use any cards from retail introductory products as part of the goal of these is to encourage people receiving a deck to purchase those starters.
For this deck, the goal is basically to power up your units by damaging them while simultaneously knocking out your opponents' units with events and abilities in order to swing for higher damage. This deck is the highest price of all the "Stocking Stuffer" series decks due to the Fallen Lightsaber. An earlier version of this deck used Guardian of the Will in place of Royal Guard Attaché but the ability to drop a 3/3 turn one just proved to be a better fit overall.
Adding money to the deck: The most obvious changes include Avenger and Snoke, but also First Light and General Grievous unit card from Twilight could be solid swaps for cards like the Clan Saxon Gauntlet or Droideka Security.
