Ummm... Water magic? Ice magic? Ice might be cool. Good for making body doubles, stealing, protecting... Seems like it'd fit him. And we need an Ice mage for Iggy to fight with >.>
Lightning magic would work to. You could do nearly everything Laxus does since a majority of the spells he uses are Lightning magic and not Lightning Dragon Slayer Magic. 
Both i've said so far actually fit very well with your character.
