I currently have two Blood Crypts.

I need:
Main-
1-2x Assemble The Legion
2x Underworld Connections
Other-
3x Ponder
4x Rift Bolt
1x Lava Spike
2x BrainStorm (I have two Ice Age ones. I want a matching set. Would really like Mercadian Masques)

There are some other small things in my WL if you want to equalize the trade value.
I also collect Imperiosaurs and Valakuts so I would have no problem taking them to stabilize.
