If this is a casual deck, then Temur Battle Rage would be great. I'd replace some Titanic Growth copies because you already have Growth Cycle. Vivian's Arkbow seems a little out of place here, and it doesn't really fit into your strategy, since you don't really care too much about which creature you're buffing.

I'd recommend looking up Boros Feather decks (both Pioneer and Standard). They would have a lot of good suggestions for Red cards.

As well, enchantments do count as targeting spells, so Cartouche of strength is fantastic.
