With a little playing around I think I like my Trio Version more.
It loses the Unstoppable, but with the Time Towers it feels like I get the the Dune Scorpions out 1 turn earlier. And that stuff matters a lot when the deck's effectiveness is increased ever turn you can get the poison on before they start dumping their hand. It also feels like I have more wiggle room in the deck. The 2nd Morning Glory keeps up the pressure.
My favorite addition so far is probably the Precognition. With only 2 Rewinds as creature control, it helps to know if you're using it at the right moment. And it's become invaluable when it comes to the timing of the Nightmare. You really don't want to play it right away if they're unable to play anything anyway. Ideally, you want to chain a couple Nightmares and Rewinds together until they die and Precognition helps you get your timing right.
(I might add more than one.)
With the latest changes to the Trio Deck, I just won 8 T50 games in a row.
So far so good.
Just need to sell off some stuff and make it in the real game for some PvP.
