White Dragon Ninja is too inconsistent, can't special summon itself, and it's never a desirable target. So what if they banish 1 of my 3 Lightpulsars by blowing up my Ninjitsu trap? Big deal. Kinka-Byo was considered, but it wasn't really worth it. Piper was the only other viable Limit Reverse target I could find aside from Trooper and the occasional Golden Ninja. This deck isn't meant to be purely competitive, by the way, it's just something I was messing around with.
