Forum:Winged Dragon of Ra's effect

What does The Winged Dragon of Ra (Effect Monster)'s effect where "When this card is normal summoned, Spells, Traps, and other Effect monster's effects cannot be activated."? Does it mean only the turn it's summoned, the moment it's summoned, or for the entire duel so long as it's face-up (making it one of, if not the, ulitmate lockdown card)? --Azure Knight-Zeo 06:51, January 24, 2010 (UTC)
