I could really use one.
Does knwoing the name help?
.... I know does in a way, because you know when you find it, but you still only have a 2% chance of actually fighting them.
I think that depends on your luck. Sometimes I face the same opponent 4 or 5 times in about 20 games.
Really annoying, when this opponent isn't a farm =)
I don't know how many upgraded cards you have but if you want Pharaos, I would recommend you to buils a RoL/hope deck with 3 or 4 Lobos and grind FGs. The chance of getting an upgraded Pharaoh from Osiris is pretty high because he has 12 of them.
The advantage is, that the Pharaos are already upgraded but it clearly takes some time and luck to get 6 of them.
