Ancient SOS issue
So I finally found a good way to get MIBs, yay! Buuuut (of course) now I seem to have some horrible luck in getting Ancient SOS's. I've opened around 150 - 180 mibs (lost track) and got 4 ancient sos's; mind you I didn't open them all at once...will that make a difference in the 1 in 15 chance? Or perhaps luck or something else plays into getting one upon opening?
Any tips, please.
