Forum:"Once per Turn" Placement

Earlier this evening, I ran into a duel between one of my friends and one return-from-the-retirement duelist. The latter one said that he can paying the effect of "Sealing Ceremony of Mokuton" during my friend's turn - that's which I disagreed immediately.

He told me to reading the "Shien" effect - and I see nothing on "Great Shogun Shien", since it was updating to current "Problem-Solved" lore, which showed "each turn" instead. Then I realized that he was meaning for "Legendary Six Samurai - Shi En", which had old lore that did NOT updating yet; though it still has "Once per Turn" in it lore.

So, let me get this straight - "Once per Turn" that set at beginning of the lore, like Sealing Ceremony's, can only work during it owner's turn while the "Once per Turn" is set in middle OR end of the lore can work at ANY turn instead, am I right? -- F  r  e  d  C  a  t  21:39, December 11, 2011 (UTC)
