Forum:Gravekeeper's Deck. please help!

Just got around to buying my structure deck: Marik and i have a few questions on witch path to choose after buying a bunch of absolute powerforce boosterpacks. I noticed that there are about 3 ways i can further improve my deck. i can

1- stick with just gravekeepers 2- try to structure around gravekeepers/ritual summoning gandalf king of destruction 3- using tuners and other effect cards to get out synchro's.

im just returning to the game so im not sure where to go from here. i have bought about 7 absolute powerforce packs and i have a good amount of cards to add to my deck, just wondering if i should stick with plain gravekeepers or add in the tuner cards and other cards that lean towards getting out synchros. thank you!!!
