red joker suit declaration timing

[Clement]

Ran into this over the weekend and couldn't find a good answer in the text.

What is the specific timing on red joker suit declaration?  This is actually relevant because of the Transmortis ability Studied Opponent.  In an opposed duel does the joker flipping model get to see the opponents flip before declaring their suit?  Or do they have to declare it "blind".  Does it matter if they're the active model or not?

Its not covered as far as I can see, although my guess is it probably is picked at the same time as you pick the card you use in the duel, so after you have seen the cards. Which might mean if the joker flipper is the active model and the non active model has a  you pick before you know the opponents suit.

Odd enough, I think I’d want to do the joker suit choosing before the “choose a card” substep.  But I might be biased from previous wordings....
