The video glosses over what I think was a subtle but important blunder - zeromh crashed a instead of a on turn 3, thereby not shuffling on cleanup and instead exposing the crash gem to the crash potato Zane certainly had in hand.
The Improvisation into Combine+Crash that quaz called out as very lucky was actually a sure thing. The crash was guaranteed as the only chip in the bag.
As far as the vs decision goes, zeromh needed to get somewhat more unlucky to lose with the crash than the minicrash. But the decision not to play Secret Move also contributed.
