I guess to me the criteria for whether or not a conditional domain source should autodraw is what the condition is. As far as I can tell, these cards are the conditional domain sources.
Sphere of Radiance - no autodraw, must sacrifice an ele creature to get domain
Quorum Stone - autodraw, must have 2 creatures adjacent to stone to get domain
Furnace of Gibil - no autodraw, must discard 2 cards to get domain
Temple of the Skull - autodraw, must destroy corpse to get domain
Treetop Dominion - autodraw, must have vision on 5 forest to get domain
Fairy Emissary - no autodraw, dim fairy and pay 2 flux
To me, the criteria for if a condition domain source autodraws is what the condition is - if there is additional cost for the domain the card should not autodraw.
Treetop will definitely give domain over time without additional cost. Quorum will give domain when you play creatures, which is something you do anyway. I agree this cards should autodraw.
Furnace, Sphere, Temple, and Fairy cost something, but Temple is the only one of these cards which autodraws. It looks like Jed almost agrees with me.
Just to beat the drum a bit more about my original complaint... Temple autodrawing is especially confusing to me. It is pretty useless as an early game domain source because there any not many corpses around at the start of the game, unless maybe a rush deck is involved or the Altar/NP combo. I was wanting to use it as a replacement for Dank Pit... 1 more flux for 1 more health and an ability which may prove useful down the road. That does not work for me, though, if it prevents me from getting more Graveyards.
