How do we play Team Galactic's Wager in Team Battle, when it says, "Each player shuffles..."?
For this card, treat the text "each player" like "you and your opponent". Under POP team play rules, this means: pick someone on your team and someone on the other team. Then only each of those players shuffle their hand, etc.
