This is a deck that I'm going to attempt to break back into standard with. I haven't played standard since the last rotation.

So please, point out the glaring faults in this deck so that I can hopefully make it into something I won't embarrass myself with.

I would go through these threads first as there are quite a few discussions about R/W Heroic decks in these forums...

All three should be relevant. I'll give your specific build a better look here later and can offer more specific card suggestions.
