So many assumptions... So to make sure I understand you correctly:
You assume you play second and and some "appropriate" point play your spy card (about 10 points for the opponent) and you are still ahead on points? For that to work your opponent has to fail at keeping up tempo hard and failed at a basic concept of the game. While there may be some players like that out there, it is hardly the fault of either the coinflip or the spy card for that happening.
In the same situration you could possibly just pass while ahead so much and either win on equal cards and use you spy card in round 2 to empty their hand or let the opponent take it for a price of 1-2 CA. Congrats, you were ahead by a mile somehow and won, what a surprise that is. I hope that gets fixed immediately?
As a sidenote: I would love to see some statistics on this whole "going second is better" argument that keeps coming up, because my anecdotal evidence disagrees with it quite a bit. While it is a little bit deck-dependent, most of mine are pretty comfortable going first in most matchups.
