Galadriel LR is also useful to start a splashed Elf, and use cards that require one. Ideas I've used are:
The Council of Elrond to play tales (powerful with Bilbo), and
Saved From the Fire to set up the
side of your fellowship (useful to start
Gandalf LoM and a
Man, a Dwarf and an Elf to play
Well Met Indeed, and to replace soon Galadriel and that UB Dwarf/Gondorian with stronger companions).
I even made a deck with both ideas, time ago: start Bilbo as RB, with
Gandalf LoM, Merry (any version),
Pippin FtF and Galadriel as starting fellows. Burn Galadriel with
SFtF asap to get an
ally (preferably
Elrond HtGG) and 2x
The Council of Elrond. Use both events to get
tales (preferably
RBoW and either
TABA or
TTotGR), without having to burn a Hobbit to get them! That's 13 twilight, but you assemble much quicker (
RBoW draws tons!), draw 1 card, and filter out 6 FP cards from draw deck at once.
Frankly, I think those ideas are hard to write in that article and there is no need to do so. But those are the only practical uses I give her. Because I HATE that version of the Witch!
