Don't get me wrong, I like this deck, but is it really a wings-bow with only 2 wings? I always use 3-4 when I make a rainbow with wings and recluses.
Well, it is always fine to have more wings, just as it is to have one more hourglass I believe. However I believe 2 is a good number without compromising the speed of the deck.
It is definitely possible to change depending on the metagame of the arena. If there are lots of shrieker rush, life rush and other rush decks without much PC in the arena currently, then more wings would be good. However currently I am facing a lot of mono-air, Sofo, and a bunch of other decks that make wings less ideal then it would be. Don't get me wrong though, wings still wins games, but I feel 2 is fine in the current aren metagame. For example, against a mono-air, or against someone who has a SoFo out, wings is pretty dead unless you get either a recluse or ulitharid or some way of dealing with said threat, and while there are ways to deal with them in the deck does not mean I always draw them, and more wings means more dead cards in your hand until then. Unlike Dim shield, 1 wings is often enough to stall for me to win the game. Of course more wings means less prone to PC, but any wings not in the field is potentially a dead card in the hand.
As for the name, its really just a speedbow with wings. Just my
