I am struggling to find a good deck to play this season. I am constantly losing to zoo and shaman.

Try Mid-Range Warrior.

NZoth Pally

Try zoo or shaman

noone can counter zoolock *evil laugh*!

Worst matchup for zoo is against N'zoth priest and freezemage. 30 % Winrate (Source)

Concede decks work great

If you're interested in Rogue decks, I've got one that does pretty damn well against Zoo, and holds its own against Shaman.

Patron Warrior, N'Zoth Paladin, Tempo Warrior, Control Warrior, Midrange Hunter, N'Zoth Priest, Renolock and even RNG Fiesta Mage

These 2 decks have been on top of the meta this month so you can't really ensure you will always have an answer with every deck.

However tempo/mid range warrior is looking like the strongest option to deal with them right now. A 2/6 taunt can be clunky for shaman to deal with, and the sweeps can punish zoo heavily. 

It seems like priest decks have a lot of answers to the boards that those 2 decks can push out but it still be hard for them to truly stabilize.

Tempo warrior is by far your best bet. And maybe freeze mage.

 +2 doomsayer in your deck => ok match-up against them with any control/mid-range top tier deck. Just hope they don't run crazed alchemist for it.

Control pally, warrior, patron,

Zoo isn't that good. It has lots of pretty hard counters. Any warrior deck, any control mage Deck, Nzoth Pally.

Face Shaman has no hard counters to any extent. Ironically Zoo is probably the best deck against it. Some of the better control decks have toss up matchups against it but Aggro Shaman can beat any deck easily with a decent draw.

Tempo warrior does really well against this. Patron does even better. Control warrior also can work. Basically any warrior deck works

I've used a variation of this (i put rag instead of greenskin, 1x execute instead of one acolyte and changed 1x arcanite to gorehowl), it appears to be very decent against mentioned decks, unless you have a terrible starting hand.

Usually win axe + upgrade and/or some pirates at start means free win vs zoo

This deck also appears to destroy mages, hunters and priests, while doing terrible vs control/tempo warrior.

As a Zoo player the only match-ups I worry about are the mirror, Mid-Shaman, and Face w/Lightning Storm teched in. In 37 games so far, this season alone, I'm 8-0 against Warrior (mostly Pirates at the lower ranks, but at least 3 of those wins were against Tempo). 

Zoo is over the top, councilman should at least be 4 health. Yesterday I lost because I couldnt even clear that ridiculous 3 mana drop with flamestrike and of course zoo has crazy burst with po and doomguards, so he bursted me down. Even against tempo warrior it's only a 50/50, I can beat them with zoo more than often. I think the only deck that is able to punish zoo and still have a chance against other meta decks is patron, which is vastly underplayed. Not even mentioning freeze mage, that deck went into the museum.
