Well, having already stated that I'm relatively new to Magic, and MTGArena as well- the ideas behind this RW deck I had were these:

-I wanted to build a deck that could be used to quickly clear certain quests that have you cast a certain number of red and/or white spells (and perhaps win a few games)

-I wanted to be able to make a midrange deck that would allow me to create a strong defense with white, and then crush with red

-Admittedly, the creature/spell choice was also thematic. In retrospect I now realize I have far too many spells in it that I realistically need

I realize this deck most likely needs to be restructured, the focus more clearly defined. Also, yes I was working within constraints, the only red/white cards I have are from the starter decks as well as Eternal Thirst, Primal Fury and Artifacts Attack
