[16] Bloodbraid Elf doesnt see much play these days as Jund has mostly become a tighter, more streamlined deck with no room for cards with a CMC of 4
Each copy grows him as well, turning him into both an engine and a threat
There is a lushness to the setting that works really well when matched with Avon's eye
Cards like these can put your opponents at a disadvantage if they strive too hard to attack you: Finally, if you want a backup plan in case you cant reclaim the monarchy, you can always play Narset, Parter of Veils or Faerie Mastermind
If you've had one Human enter the battlefield this turn (including Eowyn herself, on the turn you play her) will reward you with two more Human Knights with Trample and Haste
If a nontoken creature an opponent controls would die, instead exile it and you gain 2 life
