Haste, hold person, and coup de gras...
This is something that I'd like to use against my PCs. A hasted cleric could, in one round, cast hold person on someone that she was 5' away from (avoiding an AoO).
Assuming that the hold person spell took effect, she could then take a 5' step, and use a full round action to exectue a coup de gras on the now held, and therefore, helpless character.
I picked a cleric because they're actually useful in combat, and therefore likely to do enough damage on the coup de gras that it might actually be deadly. Hitting the held creature isn't a problem, as the attack automatically succedes.
The only trouble I see is that hold person, as a 2nd level cleric spell, has a pretty low save DC, and therefore isn't as likely to be effective against my PCs, who are, on average, 5-6 level. Against a party of 3rd level characters (3rd level being the minimum level a cleric would need to be to cast hold person, and therefore an appropriate enemy for the PCs), I think this tactic would be more effective.
There is another twist that one could use to make this more deadly:
The cleric could be equipped with a wand of hold person, allowing her to cast the spell on someone who was adjacent without provoking an AoO, and making the number of times she can try this effectively unlimited during the encounter. She would also need to have quick draw, to switch from the wand to her weapon as a free action.
