I tried to incorporate titan's and came up with this:
This version does generate more threat. I suppose the problem with both decks, however, is that they are heavily dependent on very few creatures. 1-2 titans or armagio's can be morphed, lobotomized, or congealed easily enough (antimatter could also pose a problem). That would be the only weakness I can see at this point. Luckily the rage potion can also dispense with annoying creatures like druids and ulitharid's. With that said, both versions have strong defense capabilities, and can be set up quickly. The only weakness I find with the titan deck is that it depends on pulling an animate artifact relatively early whereas the Armaggio's can absorb damage until enough rage elixir's come up.
Edit: I just found out that momentum actually negates the antimatter effect. Good to know.
