A couple things about that last post:
1) You can't attack with your own touch and the spectral hand at the same time. Drop the attacks to either 2 from the hand or 2 from the mage, not 2 from each.
2) The raven, being tiny, has to move into the fighter's square to attack. This provokes an attack of opportunity. A 7th level fighter may be very capable of killing the familiar in one hit.
Additional notes on this:
3) In order for the Raven to flank, he must approach the Fighter from the opposing space, 10 feet away from the Wizard. That means that either the Wizard must cast two separate Haste spells, or the Raven loses his Haste spell for being beyond 5 feet from the Wizard.
4) Also, if you want to use the Raven, you must cast the ESS through him (I believe, the SRD does not say and I do not have my PHB with me). In other words, you put a touch spell on your familiar for his use as opposed to one spell for both the caster and the Ravens use.
5) The Wizard had to use up two rounds casting Haste, Spiritual Hand, ESS for the Raven, ESS for himself (assuming the ESS stays up on the Raven when he casts another spell). Best case, he can only attack in round 3 if he wants to use the Raven.
6) The number of attacks they can pull off and hit with. The wizard hits with 0 attacks since he wants to get his best chance which is the hand, the raven with (1x0.95), the hand with (2x0.85). Total hits per round= 0+0.95+1.7=2.65 attacks to hit. Average damage per hit=4.5 (average of d8) + 7 = 11.5. So that's 2.65 x 11.5 * 1.05 (critical chance) damage per round, or 32 per round with no save.
The fighter is going to have to make 2.65 Fort saves or else get dazed. At the moment his Fort save is +8- pretty respectable against the wizard's DC of 16. He only need roll an 8, a 65% chance of saving. But the chances of him making it 2.65 times are (0.65^2.65), or about 32%.
7) This assumes the Fighter does not kill or disable the Raven with the AoO. Personally, I might Trip the Raven as opposed to damaging it if I knew what it was up to.
8) This also assumes the Fighter has no deflection bonus to AC items.
9) Also, this assumes the Fighter was standing around doing nothing to the Wizard in round one and possible in round two if he won initiative.
Yes, this can be possible. However, with Haste and three rounds, I can throw 5 Magic Missile spells for 70 points of damage, 5 Hold Person spells from a wand which will almost definitely kill the Fighter (making 5 DC 15 Will saves for a 7th level Fighter is really hard) with a CDG (tie him up first, that gives you plenty of time), etc.
