How Many Strategies Can Fit into a Deck?

I've had the strangest urge to build a new EDH deck for the past few days, and I've settled on Esper Control, piloted by [[Ertai, the Corrupted]]. I have so many different ideas on how I can build the deck that I don't know if I can fit them all into it. Beatdown with St. Traft, manlands, and swords...reanimator with Sharuum...Tokens with Elspeth and Co...Combo...policing the game so it doesn't end in 4 turns...I don't think I can fit it all into one deck.

Is it good to have plans A-E all in the same deck, or should I focus the gameplan more, to make it more all-in and consistent? Have you ever built decks with multiple strategies or an all-in deck? If so, how did they perform? Was it fun for you and your playgroup?
