Shepherd of the Mindless

Entomb 4 - discard a card (discard a card, {t}: Look at the top 4 cards of your library. You may choose a creature card from among them and put it into your graveyard. Put the rest on the bottom of your library in any order.)
Zombie and skeleton spells you cast cost {1} less to cast for each card it shares name with in your graveyard.
Death is like a fire, it will end eventually.
