Tricks? So far, the "tricks" you refer to include: launching legal proceedings to ensure that the UK constitution was upheld; upholding international law; holding votes in Parliament on the Withdrawal Agreement; attempting to scrutinise legislation with the world "Brexit" in it; and avoiding a "No Deal" exit because the country neither is nor will be ready for the fallout of that.
On the other hand, the tricks pro-Brexit supporters -- and Mrs. May, who is also a Brexit supporter now even if she isn't *your* Brexit supporter -- have tried include trying to shut down Parliament; trying to force an agreement through without letting Parliament vote on it; delaying that vote in the hope that the fear of No Deal would push people to support a broken deal; trying to force an agreement through even though Parliament had rejected it; trying to force the agreement through even though Parliament had rejected it twice; trying to force the agreement through even though Parliament had rejected it three times; trying to deny people a chance to vote in EU elections; delaying the process so long that the administrative process that allows EU citizens to vote in EU elections was delayed;
etc etc.
Remainers' hands are not clean in this -- in promoting a Customs Union as the solution, in particular, they are being fairly dishonest -- but there is plenty of contempt to be dished out on all sides. Attempting to force No Deal on the UK by dismissing Parliament is an approach that should have been killed off in the age of Charles II.
