I'm in love with Prophetic Flamespeaker. I kind of want to put in some build-around cards to reward double strike, but I'm not finding a lot aside from the Sword of X and X cycle. Any ideas?
Chris Taylor wrote us a great article on this exact theme some months ago.

FSR wrote an article on the heroic mechanic, which covers similar ground, and has some unique ideas of its own.

Ghor-Clan and Prophetic Flamespeaker sounds like a ton of fun though...
