Hey I've been playing with my friend and we are down to the last few trophies as well. You don't need 8 players but you do need 5. 4 to team up n one to stay opposite and take a loss. I'd love to find a few people to help us get the Plat too and I have myself and 1 other that can help. I made this account just to write you because this is the only help wanted I could find that wasn't years old. My psn is camokidd87.
