True. However, if your scales are heavily negative (e.g. drain-3 dominion), you benefit from hostile magic-3 dominions in the sense that you're at least not taking any penalty to research. If you've totally trashed your scales for a triple bless this could be important, especially because Mictlan can micromanage its dominion spread to avoid dominion kill and still contain its own dominion. I've never tried it, but IIRC Gandalf did this to get a quad bless with Mictlan and he reported it as being fun (which is not the same thing as effective, because we all know Gandalf is crazy and doesn't optimize for effectiveness).
