you should run moor tutors :)

Tutors are always a good thing, I suppose. Added Diabolic Revelation and Demonic Tutor , at the expense of Oros, the Avenger and Exquisite Blood . Are there any other good tutors that I am missing?

It's not land wipe, but what about Zo-Zu the Punisher ? It's a creature and a Manabarb for after you play your ruination? I use this combo in my Wort-Goblin deck regularly. It will also buy you time to get your fatties out. Perhaps even a Manabarb , once you have Kaalia out! You can then rely on her to drop your creatures, and reserve your mana for serious kill spells.

There is another great combo for land removal: Kiki-Jiki, Mirror Breaker , Goblin Gardener , and Thornbite Staff . Use this for an infinite land sac. combo.
