Laxus has learnt a bit of Jutsu Shiki.

The easiest way to nullify that barrier made by Laxus is to use a MBP nullifier, and Wahl's focus on Laxus and attack means he isn't really paying much attention to how he defends himself, thus making it somewhat believable that he falls for this simple trap.

From MS' tl, the red lightning thing has something to do with mercury fulminate, an explosive, not actually lightning. Mainly used as a trigger for an explosion or something. But then there was all that lightning drawing and whatnot, so Iunno. I just chalk it down to something like Gajeel vs. Torafuzar. Iron doesn't work because it's too weak, so let's use Steel. Wahl is strong against lightning, so let's use explosive lightning. *shrugs*

Nowhere close to Erza vs. Kyouka, imo.
