Forum:Cunning of the six

I have a question about the spell card "Cunning of the Six Samurai".

It says to send a six samurai to the graveyard and then special summon a six samurai from either players graveyard. So... Can you summon the same monster if nothing was in the graveyard to begin with. or could you summon the same monster as long as there was a samurai in the graveyard to begin with.

Mainly wondering because if the samurai is put int he graveyard and then brought out that is a great way to dodge quite a few problems.

Thanks in advanced.
