Jacob Z, Dreammaster

Vigilance
When Jacob enters the battlefield or deals combat damage to a player, you may search your library for a creature or planeswalker card, reveal it and put it into your hand. Shuffle your library.
{t}: Put a creature or planeswalker card from your hand onto the battlefield, if that card is a creature it gains haste until end of turn. At the
end of turn return that card to your hand. Activate this ability as a sorcery.
When Jacob is dealt damage, he phases out.
