If this card seems unplayable to you, you probably shouldnt be playing a curse deck
Much like Ghostly Prison makes it costly to attack me and creates more interactions between opponents
For just five mana, you create three 2/2 white Knight creature tokens, instantly building a board
Unfortunately, this blue enchantment costs 3 mana, generates no value, and puts in similar amounts of work to 1-mana and 2-mana mill permanents
Then, once this ability activates for a second time, you can reveal the top card of your library until you hit an Elf or Elemental card, putting that card into your hand
THB adds a new way to win the game that has never existed insofar as it does the work of the aforementioned enchantments, as well as leaving a decent body on the ground in the form of Archon of Sun's Grace
