Forum:Zerofyne vs. Swords and Steelcage

I know that cards like Swords of Revealing Light and Nightmare's Steelcage remain on the field for a specific number of turns, but what if they are negated with Zerofyne's effect? Do they remain on the field indefinitely? Does the turn count start again? --Mcoilisprime (talk • contribs) 09:16, June 9, 2013 (UTC)Mcoilisprime
