As for the build you suggested, a few potential problems I see:
Spirit Guides- They are not reliable. When you play a deck that only sees 1-3 lands a game, you can't rely on the guides to drop an elf turn one cause if it gets zapped you're screwed. They are not good, you need reliable lands that you can tap for the first two turns, which brings me to my next point...
Cradle- In combo elves, cradle is actually a bad idea. We simply do not need the mana, and if it is the only land in your hand (which is a legit concern since we usually only have 1 in our opening hand) you can't play anything on turn one. This deck needs to be built around maximizing the first 2 turns, and cradle screwes up turn one without any reasonable payoff.
Grapeshot- Tendrils is better in every way, you will never have a problem paying for it.
These are my main thoughts on the build, I can re-post my list if you want to see what I'm running.
