I tried this as an FG deck as well and couldn't make it work. Incidentally, your win ratio would have to be extremely high to get electrum/hr the same as more conventional FG decks.
Possible improvements off the top of my head: SoGs (to stall and so you EM), a lobotomizer (since you don't need the eternity until last turn and a lobo might help w/momentum), and firestorms or flood (I know this sorta defeats the deck's purpose but it might help you win more).
