favor of the mighty is so that your heavyweights doesn't get sower of temptation'd/venser'd/whatever. doesn't answer shriekmaw or riftwing cloudskate, but thems the breaks. guile seems irrelevant once i have 8/8 or 10/10 tramplers.
God draw would just be rite-rite-heavyweights for heavyweights for heavyweights for heavyweights for lovisa, attack for 40.
I just had a blog eaten by the site too. Same reason, it logged me out and then didn't keep the blog when I logged in. Bad site!
The Heavyweights are the 8/8 trample for 4 that lets your opponent fetch a creature? I don't think the Favor of the Mighty are going to do anything for you. Surely your opponent has sommething more expensive to fetch, like Shriekmaw or Bogardan Hellkite or Guile. Giving your opponent a large creature with protection from everything seems bad.
