Sounds like I already have the thoughtseizes lined up one way or another, but I'm still looking for more stuff! Including:

3 Pack Rats
4 Nightveil Specters
1 Erebos, God of the Dead
1 Lifebane Zombie
4 Mutavaults

I don't know if I have 4 Grey Merchants either, so feel free to toss one or two in for me if you're feeling generous ;)
