Djeru and Hazoret — March of the Machine Promos #221p

As long as you have one or fewer cards in hand, Djeru and Hazoret has vigilance and haste.

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.
