There's nobody else to Pass the Baton to in the Duelling League, so now's the time for Ninjask to prove that it can indeed fight for itself. Luckily, Ninjask has speed that only a select few can hope to match, and even those duellers will look like slugs after Ninjask gets a few turns. Montblanc? By the time he finishes charging his first attack, he'll be hoping his inherently inaccurate spells actually hit Ninjask and not one of its Double Team clones. Once that attack misses, it'll just be a simple job of Slashing the moogle to ribbons and proving that, even in bug form, ninja are not something to be trifled with.
