Lunalight K9

With the advent of Lunalight Scarlet Tiger in the Legendary Arc-V decks, I had a realization strike me. A Level 5 monster that can special summon from the hand when your opponent activates a monster effect? That sounds like our old pal K9! On top of that, you get a free Polymerization search, and if Scarlet Tiger is sent by card effect, you get a free special summoned Lunalight with negated effects from the GY or face-up extra deck. 

Unfortunately, we can't run Dominus Impulse due to having LIGHT and EARTH K9 monsters, but through testing, this decks work really well. If you get your Liger Dancers out and K9-X "Ripper/M", you can use Ripper/M's affect to nuke the field and your Liger Dancers don't take a scratch! On top of that, if your opponent recovers, your Liger Dancers can Raigeki them TWICE on top of Ripper/M.

GL;HF duelists.
