With no rares or upped cards, I could not find a deck I could make to beat Osiris, so taking ideas from 2 of the decks above I made the following deck, which won quite convincingly.
Lobotomise the Pharaohs, don't steel the catapults as stated he does not use them on the Pharaohs, you might want to add a 6th shield, I only had 5. Steal a hourglass or 2, use a stolen eternity on the photon to keep going when you hit 0 cards
I don't know how to post a deck idea so i just posted the code for it
here is a deck for newbies to beat Osaris
4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 4sa 55p 55p 55p 55p 55p 5if 5if 5if 5if 5if 5if 5l9 5up 5up 5up 5up 5up 5up 8pp
