All right, I went with the fattest version, and it's been working out great. Started the deck with only the 3 required upgrades, and after some on and off grinding I now have this:

So it's definitely doing work.
Another question though. I've been struggling a bit with Momentumed creatures. Sanctuaries can deal with some of the poison, but Momentum seems to usually come with a pretty high attack power.
The fully upped fat version runs Lobo's, could the semi-unupped successfully run them as well? (Maybe swapping out a Sanc for one)
