I believe the black epic is probably the best as it can be played the most consistantly 3rd turn with [card]lake of the dead[/card] and can probably even be done pretty easily on the second with rituals or other acceleration, but I don't know if a recurring [card]jesters cap[/card] is really worth losing to [card]mana drain[/card], [card]force of will[/card], [card]stifle[/card] or the card left in thier hand, and I don't really care for the cycling cards either. But, it's also the only one I'd consider because of [card]duress[/card]
Edit: I guess stifle would be a good thing!?! oh well
