Hmm, I might want to switch off purple then, I am known on these forums for my love of purple…
I can go through your thoughts/techs in a mo and see if I can give advice, but I’ve not very familiar with the blue side of this matchup. Without going through your thoughts quickly, I will say that going down so many cards to break my tech 1 on T3 was probably a mistake. Without continuous pressure, purple can easy bounce back from that, as my cards get continuous value over time (Nullcraft, mox, Battlesuits), and that plasmodium entering a turn later guarantees I have large bodies that you have to play around.
Purple is the king of controlling tempo in a game, and hence trying to out tempo it with one big turn doesn’t work too well, its designed to be able to flex and spring back. Blue doesn’t really have the aggro required to race it, my tech 1’s are generally just as good value wise but with more tempo so forcing a tech 1 game is not wise. I think you might need to go for a tech 3 race at some point, your tech 2 pressure generally isn’t keeping me off tech 3 (as as this game shows, if I can spend 5 gold on a tech 3, and 5 gold on a 4/3 and keep them both alive, then I had so much board control that I could have used any win con, that’s how control of the board you ceded when you went down on cards T2/3.
EDIT: @flagrantangles actually I found the problem, going back over the game, on T4 I accidentally didn’t pay for a stewardess somehow, and that probably tipped the game… Given legion has also pointed out to me that I accidently failed to pay for a temporal research in an earlier game, feel free to attribute those losses to me accidently cheating… sorry about that.
