Come to think of it... with the quality of his illusions he might be able to employ them in a fight, making him a lot more dangerous.

Against Laxus he most likely couldn't do it, because he was already maintaining a large-scale illusion of the battle-arena and the illusions of him and his team standing in the ranks.

But if he could use the illusions in the fight, he could make the enemy believe him to be at a completely different spot. That way he could avoid being hit (like Rufus and his memory clone, or whatever he used to make Nullpudding miss him) and move in a position to hit the opponents weakspots.
