You can also communiun priests with the Slave/Crystal matrices - if you split an 80-priest squad between the two, even using little H2 indy priests, you are talking about 40 effectively H6 priests. Using those nifty H4 priests some nations own, it does even better. Add a staff of storms and a bunch of lightning-immune lifeless chaff (e.g., mechanical men) to gaurd the priests; you then have penetration 2 vs. undead/deamons that does a fair chunk of damage to a rather wide area. A few banishments from the priests and the vamps will likely rout en masse (those that don't perish; after that, the only targets for the banishment is your undead commanders, so they are gone soon after), the storm demons will also fall rather quickly to the same thing (especially as they can't reach the priests due the mechanical men gaurds). The priests also help with the dominion war (which, by the way, if you are winning as a pre-requisite to the strat, makes much of the strat icing, no?) so they will be on hand anyway. After that all that is left are some anti-SC SC's (or anti-SC thugs) to deal with your SC's.

Other possibilities are heavy use of anti-commander stuff (assasins and assasination spells, to strand your vamp army), taking your capital to neutralize the immortality, other raids (you did say you were commiting your pretender, prophet and most your forces to a border dispute on dominion at a specific location, to push your dominion into opposing territory; that pretty much means your opponent can arrange to raid pretty much at will; sure, you can do the same thing with your vampires and vampire lords - but then you can't drag the air queen SC and storm demons along to deal with the vamp counters) to burn your temples and cut your dominion elsewhere. Likewise, stealth priests (anyone can find druids, a few nations have stealth priests)

Don't get me wrong - the vamp horde is a good strategy; but like any strat, especially those relying on a particular unit / commander type, there are different counters available to most nations. Dominions is a surprisingly balanced game.
