Currently, bluffing interaction (like instant-speed removal or counterspells) requires turning on Full Control. However, Full Control forces manual priority passes on every single phase and trigger including upkeeps, draw steps, and personal main phase actions.
Experienced opponents easily spot Full Control because its timing pattern differs completely from normal MTGA priority stops, rendering the bluff ineffective while needlessly slowing down matches.

I am requesting a Smart Priority Bluff Toggle that allows players to instruct the game engine to mimic holding specific cards from their deck/sideboard.

Implementation idea:
The player would have a menu with toggles for each card name in their deck. Instead of giving priority based on player's hand, the game could give priority based of the list of toggles.
We can imagine a static / default list attached to the deck so it s more conveniant.
