I'm unsure why people think why the Izzet ability TRIGGERS on whenever you are dealt damage (by an opponent). That doesn't look like a key mechanic at all to me. Look at the other mechanics, they work whenever *you* want them to work. It might be a triggered ability on something *you* do, but it will probably not trigger on an opponent doing something, because that is simply unplayable.
Once again, I'm saying: look at what red and blue have in common and start looking for a key mechanic from there, because I think that *will* work and you will get closer in guessing what it will be.
