Flamespeaker is a house! I was playing a similar deck online, but would sometimes just run out of gas. Flamespeaker is a great solution, and a good way to be able to attack in to a random trygon without worrying about losing creatures.
In my list I cut stoneforge package, revoker, moved cage to SB, and I'm running 4 magus of the moon and 4 stony silence instead. I've been playing this a lot online and an uncounterable magus just seems to end so many games, especially if you can keep them off their moxes/lotus with stony silence. I also like the surprise factor of magus; no one seems to be expecting it, and when it hits very few people are prepared to deal with it.
