Forum:Creature swap help

I was playing with my friend and he haw playing with a The Six Samurai deck and i was playing with a Dragon deck and i activate creature swap to swap my Masked Dragon and his The Six Samurai - Zanji and i said i can keep his six samurai until the rest the duel and he said that i couldn't keep his six samurai because he said then only thing that couldn't switch was the Battle Position not the field position. And what i'm asking his what he said is truth or not? and i can keep his six samurai until the rest the duel?--Shiker&amp; (talk • contribs) 00:44, April 28, 2011 (UTC)
