Here are my initial thoughts. I deliberately avoided what others have written so we can get a variety of opinions.
Mrblonde vs

Jaymanfu
My guess is they'll have two grabow decks, two pestal decks, a bunch of EQs, and 1-2 Entropy duos with discord. The immo deck beats all of that handily unless you drawfail, plus it's unexpected, but I’m recommending that go to xdude. The grabow will be good too.
Kevkev vs

Pikachufan (lieutenant)
I expect Aether decks to change more than any other team. A lot of new blood and Higs is creative and motivated. Unfortunately this means I have no idea what to expect. My guess is they’ll have 2x pestal and immophoenix. Regarding the matchup I feel like purifies could be coming. D/BH is interesting and would be completely unexpected.
Xdude vs

TNG
Gravity will have two D/BH decks, two grabow decks, a momentum deathstalker deck, and a phoenix deck. D/BH where they try to stop us from reaching 7 quanta is the strongest possibility imo. Countering discord requires you to either destroy them, block them, or use nova/immo to make discord less effective. The deflag version of the immo deck would be win for blonde but it’s even winner here.
Daxx vs

Vagman13 (lieutenant)
Others have given this matchup more thought than I have, so I’ll defer to them. I think DoSA has some merit against Entropy, though, and we’re going to have to use more than one deck against them eventually.
ICB vs

Edunavas
The three most likely decks we'll face are grabow, FFQ/hope, or a fire bolt deck. The bolt deck they loved last War would be brilliant cuz they'd get around bonewall and have deflags for arsenic, our two most dangerous cards. Maybe something like the RT deck I recommended here (
http://elementscommunity.org/forum/index.php/topic,23479.msg324757#msg324757) would be good given those possibilities?
Xnoize vs

Majofa (lieutenant)
This is why we have the fire counter. I agree that a bolt deck is likely and maj has I think four fire marks, but I still like your chances. I stated earlier that Fire is likely to stick purifies in immo decks, but the fire counter can still win by deckout.
SteppingStone vs

Acsabi44
They have grabby rush and solid Darkness duos at their disposal but my guess is we’ll see a Light duo that could include any of the above: titanium shield to nullify arsenic, sanctuary, miracle, stoneskin, EQ, and wardens. They also stall well with Water and Entropy. D/BH works against stalls but fails definitely against sanctuary, probably against Darkness duos, and maybe against grabby rush. Possibilities: fractal upped spiders, sundial deck with upped arsenics, the grabow with EQs.
Marvaddin vs

RootRanger
I sorta like a Death rush with either Darkness or Fire splashed for PC here. I feel like we can load up on critters and ignore CC and we might still be ok.
Regarding the Event CardThis round we win six cards or lose six cards. If we choose to buy three upped cards, we need our winrate to be 1/12 or 8.33% higher to break even. 8.33% is a lot to expect out of three measly upped cards, so in general I agree with not buying upped cards. If we do see a matchup where upped cards might make a large difference in winrate, we should pull the trigger. For some reason Step’s matchup could feel that way to me.
