I've never played team dixit, but here's my interpretation:
See the storyteller's role on the basic game
If the storyteller's role is the same as the basic game, he/she first selects a card, and then tells a story.
Handing the image cards to the Storyteller
After having listened to what the storyteller said, his or her
teammate hands the storyteller an image representing as best
as possible what was said. The 2 players of each team then
agree as to which of them will hand an image to the
- The storyteller's teammate gives the storyteller a card.
- Each remaining team decides which team member gives the storyteller a card.
Vote and Scoring
(...)The vote and the scoring follow the basic rules (do not use the voting and scoring rules for 7 or more players).
Only the players that didn't put out a card get to vote, and the scoring follows the basic game.
The storyteller and the storyteller's teammate are two different cards. Voting on the storyteller's teammate's card would still give that team the bonus point(s) for earning a vote.
So to illustrate with an example, say there are three teams A, B and C, with players 1 and 2.
A1 is the storyteller.
A2 is the storyteller's teammate.
A1 picks a card, and tells a story.
A2 gives A1 a card.
B1 and B2 discuss, and decide that B1 should give A1 the card.
C1 and C2 discuss, and decide that C2 should give A1 the card.
A1 now shuffles and reveals the 4 cards.
B2 and C1 vote amongst the 4 cards.
Both/neither vote for A1's card: teams B and C earn 2 points
Other cases: team A and the correct team earn 3 points
A2, B1 and C2 are eligible for bonus points if their cards were voted on.
