Sunforger is awesome.

epajula, thanks for the suggestion, but this deck only plays 2 Instants so Sunforger doesn't really seem worth it.

Have you considered Blinding Angel? This will skip the opponents attack phase. I use Angel's Trumpet and either Dolmen Gate or Iroas, God of Victory for free swings on my turn and to tap the opponents creatures.

My deck has a pretty heavy prison slant but there might be some other creatures you could consider if you wanted to take a look.

I feel no Boros Angel deck could exist without Razia, Boros Archangel. It's not actually that good but sometimes you just need to take that one for the team for the sake of flavour.

Heirloom Blade, Vanquisher's Banner, Cavern of Souls, and Path of Ancestry seem good.
