2 Ewers and 2 Andurils is perhaps too much, though
Nenya luckily provides a good way of cycling them. I think I would cut 1 of each in favour of vitality adders like
The Tale of Gil-galad,
The Saga of Elendil, which seem to support your strategy quite a lot.
There's no point running
LotC unless you have 4 of him, in my opinion. I think it makes more sense not to start Glorfindel (putting another Elf or 2 in the deck like Orophin and Rúmil :hey: ) and starting
Greenleaf and
Leader of Men. This way,
Narya can be played first site for maximum burden removal. Also, I would strongly consider running a copy of
Foe-hammer to make sure you shed those burdens.
I wouldn't bother with
Arwen's Dagger,
SotF is better. I especially wouldn't bother with 1, let alone 2, Phials because you need to lose some cards as this deck is too large and has no drawing capacity. I would replace both
Weapons of Lothlorien with
Servant of the Secret Fire (which is fine to have 4 of when starting Gandalf) because it's just awesome. Also, 3
Gandalf's Cart seems excessive. If you removed those cards from the deck, you'd be far more likely to draw the possessions you need at the right time!
