if you didn't put water 3 on your pretender
and if you did, empowering him in blood or starting him w/ blood 1 might be more efficient.
Again, a lot of these decisions affect others. One reason to rush for ID's is to provide a needed military boost to Mictlan fairly early, in order to compensate for a perhaps otherwise slow start. However, w/ a bless strat, especially a bless strat backed by an SC, early expansion isn't so much an issue, and grabbing all the IDs not so important (if there is even another nation looking like they're going for them). So w/ a bless/SC strat, I would normally just go to const 6 before heading for the blood summons. by the time i hit the IDs/ADs, any and all still available become mine.
Oh, and beating up on Abysia is a good idea too
