http://elementscommunity.org/forum/round-7/(entropy-gen-)-iancudorinmarian-3-2-kaempfer13-(death-lt-)/ meh, fine perhaps this is wrong here with only 11 quanta sources, but it got really close
http://elementscommunity.org/forum/round-7/(life-liutentant)-vangelios-(sub-manu)-3-2-patient666158-(death-salvage)/ yh ok that wouldnt normally win, but still it was a 2-3
http://elementscommunity.org/forum/round-8/(aether-upgrades)-theonlyrealbeef-3-1-(death-salvage)-(sub)-patient666158/ I prepared for stall, the mindgate version didnt work out in the 2 testmatches I played, I used dials differently there however, didnt realize the stall would win by damage. Without mindgates its an easy matchup, with them I still think we were favoured, but tough call. Was going to put it in real bad beats, but perhaps my testing just didnt inform me well about how threatening mindgates are. If someone wants to test it, its quite fun to play if you dont have a war to lose. You really need to know what you are doing though.
http://elementscommunity.org/forum/round-8/(life-upgrades)-spielkind-3-1-kaempfer13-(death-lt-)/ ok purify turned this from 70%winrate to sth below 50% it but it could still be won, even a game where puri was drawn.
http://elementscommunity.org/forum/round-4-249/(death-gen)-danieela-3-2-blacksmith-(earth-gen)/ without discord+3 nova near guaranteed win

Some of these have been mentioned above as they became close rather than being a near guaranteed win.
This only mentions those losses which we would have won if I had chosen one of the decks we closely considered, everything not mentioned in this salt spoiler we just lost fair and square.
http://elementscommunity.org/forum/round-2-247/(time-lt-)-(sub)-naii_the_baf-3-2-blrawen-(death-buccaneer)/ poisonous mummies (with wall) eats it for breakfast. thought it might be to obvious, I may have actually used the deck here if I hadnt had discussed it with Dani and she strongly expected them to expect it, but hey its on me I did agree eventually.
http://elementscommunity.org/forum/round-3-248/(air-lt)-phoenix1211-3-0-(death-lt)-kaempfer13/ this might not belong here, as I didnt test this one properly and thought the deck we used would beat all rushy decks, but rtmummies would have worked, which I considered very briefly (I didnt know it beats darkdom back then though, thought it close).
http://elementscommunity.org/forum/round-4-249/(life-sideboard)-vangelios-3-0-kaempfer13-(death-alchemist)/ I saw frogtal coming, but darkdom went vs fire already and I didnt have the opportunity to properly test whether this deck would work or we had a better counter.
http://elementscommunity.org/forum/round-4-249/(fire-gen)-worldwideweb3-3-0-blrawen-(death-lt-)-(subbed-by-patient)/ I thought they would use their only counter to rt mummies here, fractix. Rt-mummies would have worked and I strongly debated it, since it even has a small chance of beating fractix with dims (and certainly without dims and lobo).
http://elementscommunity.org/forum/round-5-250/(aether-lieutenant)-theonlyrealbeef-3-0-(death-general)-danieela/ I considered deflagsplash here, which definitely would have been closer, though it might not be enough
http://elementscommunity.org/forum/round-7/(entropy-gen-)-iancudorinmarian-3-2-kaempfer13-(death-lt-)/ I considered stall here and it would have worked (I think, sofo messes with it quite a bit, but i dont think it has enough consistent damage for 2 sofo to be enough, though its just enough to deal with all sancs...).
All of round 8, the respective mods for stall i had in mind would have worked vs each opponent. Not really a bad choice since the one it went against it was perfectly reasonable against and we didnt have more copies of it and with that rng it doesnt even matter anyway.
