The card Brain Transference reads:
You and a player of your choice switch seats at the table (leaving your hands). You each take over the other player's entire position in the game, as if you were in that position all along.
Your turn ends immediately. The person next in order from your original seat goes next unless that's you, in which case the player after your new seat goes next.
(Leaving your hands) wording in card description is unclear to me. When I change seat, do I keep my hand of cards or also switch cards with my opponent?
