Yggdralkin, Bane of Woewedt

When Yggdralkin, Bane of Woewedt enters
the battlefield, reveal cards from the top of
your library until you reveal a non-creature
card. Put all creature cards revealed this way
onto the battlefield under your control.
If you do, discard your hand. Creatures that
entered the battlefield this way gain haste
until end of turn.
