Is it legal or ethical for 3 Wizard players to share views of their hands during play to ensure that a fourth player looses? If I have suspicion of this unethical and unfair behavior - perhaps by use of Teams or joint cell phone FaceTime Calls, besides not ever playing with these shady characters again, is there an adjudicating authority that can observe certain groups of players that act as a skilled set of collaborators by reverse card-counting and collaboration, to make a single honest player have a humiliating game of Wizard? Or am I just paranoid and it is just coincidental the each of my 3 opponents made their last 5 bids exactly and systematically while the almost certain winners in my hand were craftily defeated by each of my opponents, taking turns, that seemed to me to be orchestrated by direct communications (not on GBA interface)???

Has anyone else noted this proclivity in playing Wizard?

Did you check the game record? From my perspective, the game you mentioned looks like a table of 4 randos.
