Forum:Chain Coil

I've noticed that the Japanese Chain Coil has no text stating that Coil must remain face-up on the field for the boost to stay, and the OCG rulings state that the boost on the monster lasts whilst the affected monster stays face-up on the field, regardless of whether Coil goes on or off the field. However, the TCG wordings state that Coil must remain face-up on the field for the boost to last. So, in this case, does the OCG ruling take precedence, or the TCG wording? And if the former does, is it a case of BKSS? --Gadjiltron 04:41, 16 December 2008 (UTC)
