You've both made incorrect interpretations of different rules at different points.

Firstly, if a blocker is declared, both players DO gain priority prior to damage being dealt, so you do have the opportunity to cast Druid's Deliverance. Point to you.

However, let's look at Druid's Deliverance, a two mana instant that reads:

Prevent all combat damage that would be dealt to you this turn. Populate.

This card prevents all damage that is dealt to the player casting it, and then performs the keyword ability Populate (which is not relevant to the question as asked). The important element is that it only prevents damage dealt to the player casting the spell, and does not prevent any damage dealt to his or her creatures.

Compare the wording to the quintessential damage-prevention spell Fog (trivia - spells that perform like-functions are colloquially known as "Fog effects"):

Prevent all combat damage that would be dealt this turn.

Fog prevents all damage that's dealt to everyone and their creatures on this turn.

So in the situation that you describe, the appropriate game state at the end of combat is that neither of you has your respective creature, but if you had a token creature in play you now have another (as per Populate)

Thanks for clearing that. I'm glad to know I'm right about casting an instant, as he was pretty obnoxious about it.
