What are some good cards to have in a spellcaster deck and does a deck of all spellcaster type monsters work?

Actually the best route to go for a spellcaster deck is building a Gravekeeper's deck. It's reasonably priced deck, as in all the cards are cheap. (just go buy x3 marik structure deck and your 3/4 of the way there) Recently gravekeeper's just won a YCS.
