Forum:Can you not special summon a monster from the deck, by its own effect?

From a last duel we have with Sheimira, one of the yugioh duelists here tells us that you are not allowed to special summon a monster from your deck, like Gigantes, how about Aqua Spirit with the same condition, Chaos Sorcerer and others so pleas help me guys. 122.53.131.32 06:54, 7 March 2009 (UTC)
