Went undefeated with this deck (in terms of matches; ironically every round saw me winning with a 2-1 record), and then IDed in the final round. Which worked out well for me, as my opponent crushed me with Horn of Gondor (which I did not see all day until the second friendly game of that last round, when I got it going a touch slower than my opponent and also didn't have anything like The Black Breath which they used to wipe my side).

Started with 17 lands, but swapped one out for the Palantir after round 3, since I felt like my landcycler birds and general card draw were enough to justify going down a bit. Generally seemed to work out OK.

Anduril was nuts. Saved my bacon in round 1 after I lost a grindy, 30 minute first game and was able to put it on my Took Reaper on turn 4 of game 2. Winning that game quickly let me get into a winning position by the time game 3 went to turns.
