But those characters couldn't do it without involving another mage. Lucy does this with her spirits AKA her magic. Also the Spirits have already shown to be able to do similar things during this entire series. Also what does plot have to do with amount of magical power a mage has? Lucy was never out of magical power when she performed Urano Metria she was just low on magical power. There is a huge difference. Also summoning the Spirit King and Summoning 3 spirits at the same time means she has an enormous amount of magical power. Because Angel could summon 2 spirits at a time she was considered to have a huge amount of magical power it was stated in the Manga.
