It's funny I was just messing around with Liquid Shadow + Earth last night.
If creature + Liquid Shadow is all you want to focus on, then:
You could try something like this:

5uk 5uk 5uk 5uk 5uk 5uk 5uk 5uk 5um 5um 5um 5um 5um 5um 5uo 5up 5uq 5ur 5uu 5uu 5uu 5uu 5uu 5uu 5uv 5uv 5uv 5uv 5uv 5uv 8pm
Which doesn't EM all that often but is a very cute deck. Something I made a long time ago.
Or what I was using yesterday:

58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58o 58r 58r 58r 58r 58r 58r 5um 5um 5um 5um 5um 5um 5up 5up 5uu 5uu 5uu 5uu 8pt
Which is a lot less reliable but more stylish with more EMs. You could also play it with Shriekers for faster attack but you'll be much more fragile.
But I think your key cards here are EQ, Devourer, and Liquid Shadow. Also Gargoyle maybe? I'll see what I can do.
