Veil Warp Dragon

Devoid (This card has no color)
Flying, shroud, haste
Whenever Veil Warp Dragon attacks, you may
pay {u}{b}{r}{g} and have it lose shroud and devoid
until end of turn. If you do, exile your library
until you exile a non-creature card. You may
cast it until end of turn. Veil Warp Dragon
gains +1/+1 for each land exiled this way. Shuffle
the rest into your library.
