So I need some modern stuff, but all I have is Standard. I'm hoping someone out there can help me out and get my first modern deck built. Here's what I need to finish off my modern deck right now, in order of priority:

Mainboard:
4x Arid Mesa
4x Fire-Lit Thicket
3x Grove of the Burnwillows

Sideboard:
1x Ethersworn Canonist
2x Fulminator Mage
1x Avalanche Riders

Mainboard low priorities:
3x Noble Hierarch(I'm currently using Avacyn's Pilgrims, which is fine until I get into a bigger tournament setting)

Some of the good things I have are:
1x Boros Reckoner
1x Obzedat, Ghost council
1x Watery Grave
4x Drowned Catacomb
1x Snapcaster Mage
2x Aurelia
3x Jace, Memory Adept
1x Angel of Serenity
2x Blind Obedience
1x Prime Speaker Zegana
2x Duskmantle Seer

Any help is greatly appreciated. Some of the stuff I listed here isn't in my tradelist, but if you propose a trade with it in the chat, or say here you want it, I can add it to my tradelist for you. They're in a small deck that I'm throwing around that I am more than willing to tear apart for my modern deck.

Thanks!

I just recently build the deck that you're assembling.

My suggestion is to use Deathrite Shaman instead of Pilgrim until you get the Nobles.

Best of luck!
