Basically when you use Benten searches you can search out Lo, the Prayer of the Voiceless Voice, which searches Barrier of the Voiceless Voice, which then searches Saffira, Dragon Queen of the Voiceless Voice, which she can discard herself and mill off Meteornis Drytron (which recovers itself) to search any Light Dragon or Light Warrior ritual monster, including Ohime, ritual Saffira, Hearld of Ultimateness, Sauravis, etc. and you can banish Saffira (the effect monster one) from the GY to ritual summon said monster you searched if you don't want to use the free Meteornis Drytron you milled. All in all, Voiceless Voice has two good cards and they're good for only ritual decks, which only one exists. The other combos in this deck are just normal Drytron things.
