H: 3x Jace, AoT - Willing to Trade Down to Get Cards I Need

I need quite a few cards for a deck:
Restoration Angel
3x Thalia
2x Entreat the Angels
3x Heliod
3x Terminus
2x Gavony Township
3x Kitchen Finks
2x Banisher Priest
2x Wall of Omens

Also really need

2-3 Abrupt Decay
4 Sulfur Falls

So what's this trade down stuff about? I'm more than happy to trade the Jaces at $16-17 each depending on what comes back. It's easier than listing them on eBay and then buying the cards I need and getting hosed on shipping from a bunch of different sources. If I can get $45 in value from one person with mostly the above cards, I'll be happy to take that (once again, saves on shipping).

Thanks!
