Some people are underestimating Lucy... She is strong and it takes great amount of magic to summon any spirits. In the Tartaros arc she summoned not only 3 spirits at once but also the CELESTIAL SPIRIT KING. CSK even battled Mard Geer but since it was Lucy who SUMMONED him it was Lucy vs Mard Geer and the fact that Lucy beat JACKAL while CSK was on par with Mard Geer and even SAVED all FT members. So yeah.... Lucy is pretty damn strong.
