Board Game Arena

Is it considered a valid bluff if it's impossible that the next player has the supposed card? I would say it follows the main rule of finesse "what happens if I don't play?" And is therefore valid. But had a disagreement so I'll ask others opinions here. For example, A clues m5 on D's hand...

Looks nice! Much thanks

I prefer the slower animation as well for a couple of reasons.
It's easier to miss what happened or what card was discarded.
It feels more forceful, taking away from the calming effect of the game and feels slightly more stressful to play.
Thanks!
