Lance and Dragonite

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

Whenever Lance and Dragonite 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.
