As long as you have one or fewer cards in hand, Djeru and Hazoret has
vigilance (Attacking doesn't cause this creature to tap.) and
haste (This creature can attack, and as soon as it comes under your control.).
Whenever Djeru and Hazoret attacks, look at the top six cards of your library. You may exile a legendary creature card from among them. Put the rest on the bottom of your library in a random order. Until end of turn, you may cast the exiled card without paying its mana cost.
