User blog:General MGD 109/Who's most powerful?

In his first appearance, Cornelius Sigan was described as the most powerful soccereer who ever lived, and in that episoded he should this to be true, he performed magic greater than anything else we have ever seen on the show, (I mean, he made himself immortal, he animated every gargoyle in camalot, and could still control them, the most we've seen any other socerer acomplish, is animate three snakes.)

However in more recent episodes, Merlin has been called the most powerful soccerer ever to live, and admitadly he had also shown great feats of power, so the question I'm wondering is, who is more powerful, Merlin or Sigan?

To add a third side to this question, in there duel, Morgana showed she is about as powerful as Merlin, only less experiance in a magical fight, so now out of the three of them, who is the most powerful, Merlin, Morgana or Sigan? What do you think?
