Gotta agree with OG_Gleep : as I said, Mictlan using blood spells is cheating, given the discussion that went on and the obvious intent. The fact that there's a technical loophole doesn't mean it isn't cheating. But maybe Mictlan has a politician or lawyer for pretender?
( Perhaps in the future, blood can be modded out : if all blood summons were made 500 blood slaves, ditto all items, no one would even be tempted. )
