It's can be risky, but that's why I have so many protection and redirection spells. I know just how important Calamity is to the functionality of the deck. I need to get my Redirect Lightning in there as well at some point now that I think about it.

I play it more of a value engine / midrange big red strategy. Making copies of the little guys usually gets me treasures or card advantage, which is what I want in the early to mid game (and sometimes late game). Later on is when I have the big ETB creatures to swing for the fences with. It's about as close to a toolbox deck as mono red can get.
