Apparently a deck consisting of:

1 x Skaab Ruinator
1 x Skaab Goliath
1 x Undead Alchemist
1 x Makeshift Mauler
1 x Abatoir Ghoul
3 x Armored Skaab
2 x Deranged Assistant
2 x Ghoulcallers Chant
1 x Ghoulcallers Bell 

And plenty more zombies. Not enough threats I suppose, perhaps not enough removal to get them through? Lost first round and I'm not sure I'll try the zombie idea again. I thought it ought to work, but didn't seem to.
