Why Tirek with Discord magic couldn't defeat Twilight? Discord is crearly more powerful than all alicorns together but suddenly Tirek with only the magic of earth, unicorn and pegasus ponies was able to steal all his powers. It doesn't make sense at all how Twlight could stand against him,I like to think that everything was planned by Celestia and Discord from the beginning(since most time of the show Celestia let Twilight solve all the problem like if she has a bigger destiny and they are preparing her). I thought that the spirit of Chaos and disharmony was the strongest force in Equestria after the "magic of friendship" What do you think? Am I overrating him a little bit?
