A few cards that should be either in deck or in Reserve (although I'm not seeing too much Reserve access):
The Winged Leopard (PoC)
Loaves and Fishes (I)
Gifts of the Magi
Kindness (EC), swap for Di one
The Deceiver + EC's in Reserve (i.e. Goliath, B/G Outsiders, etc.)
Christian Martyr (swap for DoN)
Wages of Sin (FoM), might be tough to get if you don't have one but if you can get one it's really great as it can help you get Abom faster.
Paying Taxes in Reserve, helps compensate for no DoN. Can be grabbed with Heart of Depravity or Wages if you get one.
Some cards you could take out for them:
- Hostile Environment, the reason the Nats 2015 deck ran silver sites was because Stoic Philosophers would protect Arrest in Gethsemane (protects LS's from Angels and Doms) from discarding itself. Since you're not using Arrest it's not really necessary.
- Hormah, it can be handy, especially with Site Doubler, but probably not worth it overall and it would be better to have LS's to get you to your defense faster if you have them (i.e. Lawless (CoW), Imitate (RoJ), etc.)
- Danites Attack, could be sneaky to snag a City but probably not worth the slot
- Fortress of Antonia, I'm pretty sure Antiochus is O.T. so Alexander would be your only N.T. warrior if I'm remembering his reference correctly
- House in Bethany, I don't think I've ever used this card to much effect. I guess it could be good with all the splashed demons going around but that's probably something I would cut.
Some ideas for the Reserve, if you add Covenant of Prayer to the main deck you can have pretty much anything in there, but other ideas would be adding Faith to the main deck and Faith of Gideon, Samson, and/or Jephthah in Reserve. The Emmaus Road and any fitting Star cards for PoC wouldn't be a bad idea either.
