Venrashai's Influence

Reveal your hand, then sideboard a random
creature card from among those cards. If you do, reveal cards from the top of your library until
you reveal a creature with mana value less than
or equal to the sideboarded card's mana value
and put it onto the battlefield. It gains haste and prowess until end of turn. Put all other cards
revealed from your library this way on the
bottom of your library in any order.
