Y'know, there's a 1/3 chance that you have a 1 turn sleep, so I don't see what's worth complaining about especially since you had another 1/3 chance of rolling Thunder on the Garchomp (hence doing nothing) and disallowing 49 from sleeping another 'Mon had things played out differently.
I guess your Ferro got crit which would mean more Spikes in the long run, but I don't see how that affects Gyara or Gengar's ability to clean late game at all
But fine, I mean, you got an equally annoying crit on the Chomp later in the game anyway (which would've forced another sack), which you left out of your analysis. Well, what can I expect from a player who leaves their win-condition in against a potential OHKO taking what, an 85% chance to autolose the game, and then gets rewarded for it, and THEN complains after he wins.
I have nothing against you personally, but don't try to cover shit up lol
