Well there isn't really much to gain by keeping it secret from you guys, here's what I was thinking.
5f6 5f6 5f6 5f6 5f6 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oc 5oi 5oi 5oi 5ol 5ol 5ol 5ol 5om 5om 5om 5om 5om 5p0
(Note: not really sure which cards I would take upgraded. The OE to EE for more damage or Deflags to Explosions it seems to me.
What I like about this is that most gravity decks seem like they will be slow enough to allow this to get established, wipe out all of the creatures via OE, and finish with the UG. Just an idea anyway.
Note: The nymph could just as easily be another UG, and that might be more appropriate for this matchup, given the low HP of the nymph.
