I'm looking to rage quit/ trade away Modern Twin for Modern Burn, specifically the Nacatl list. I still need:
Eidolon of the Great Revel x4
Goblin Guide x4 (promo preferred, but not required)
Grim Lavamancer
Wild Nacatl x4 (promo only)
Atarka's Command x4
Boros Charm x4
Bloodstained Mire x3
Sacred Foundry x3
Stomping Grounds x2
Wooded Foothills x3
Kor Firewalker x3 (promo only)

I have the entire Twin list from Modern for trade, and would be willing to trade up to 2 of the Scalding Tarns for the right deal. Shoot me an offer if you're interested in making something work!
