Neo Cortex, the Maniacal

When Neo Cortex enters the battlefield, you may search your library for a villain creature card, put it into your hand and shuffle your library.
When you cast a villain creature card, you may pay {2} less to pay its mana cost. If you do, it has summoning sickness until the end of your next turn (creatures with haste still can't attack).
{t}: Deal 1 damage to target tapped creature.
