Couple trades

I have a snapcaster mage  + some value I'd like to trade into a Wrenn and Six.
I have a verdant catacomb I'd like to trade into 2-3 Prismatic vistas.

Looking for the following:
Magus of the Moon
Crumble to Dust
Field of the dead

I'm OK with sending first since I only have 1 local trade on the site.
