I think Loke just meant that in general, zodiac spirits use a lot of magic :P. Then again... Lucy's only spirits that can fight are the zodiac's. I was reading the pages of the celestial spirits, Virgo's summon cost is 43, while Aquarius' is 100. Also as seen with Virgo, she's ok in terms of combat, but I believe Taurus or Capricorn (though we haven't seen Lucy ever summon him... but he was hyped at the time :P) would be better for combat purposes.
