And not just any trick, but a beautiful trick, one that requires someone to understand the move order, turn phases, card interactions on the move order, and what Warzone displays to your opponent.
It's a trend that has been going on for years. I call it 'simplification'. Over the years, luck percentage was eliminated on the ladders, after which came Weighted Random, which was replaced by Straight Round. The move order standard went from Random Move Order to Cyclic Move Order (and NLC in some cases). Attack-only moves were then removed, prerequisites were shaven down to the most used ones, etc.
The strategic community didn't like most of those changes at first, but that community got a lot of new players to whom it made more sense to have these predictable and logical settings. While I love Weighted Random on some templates and think it can add a lot to a template like the old 0%WR ladder, the general opinion has shifted to the setting being luck based and not strategic. There is no need for Fizzer to embrace a legacy playerbase or the old guard when the new settings are more enjoyed by the newer - and majority - of the playerbase.
These 'tricks', like a phantom move, a dirty gift, a Timinator Blockade or the JZ Delay might follow suit someday. The argument that it only adds depth and doesn't hurt anyone was shown as non-important when attack-only got removed from the 3v3 ladder.
I would love for these quirks and tricks to remain in the game, but it serves a very niche playerbase.
Conclusion: make the 1v1 ladder 0%WR again! :)
