Hey guys, here's the guide. I'm still going to update it when I change a card or know more about certain matchups.
I love this deck and I wanted to share it with you. If you don't have a lot of these cards, you should be aware that this isn't a meta deck. So spend your dust wisely :D. It is a ton of fun tho and i have a good winrate around Rank 5 with it right now.
This deck is all about the new cards Portal Keeper and Portal Overfiend that can be combined with Augmented Elekk and later in the game with Shudderwock. You fill your deck with portals that generate you great tempo in the mid- and lategame stages of the game and they can be used as a win condition with The Storm Bringer.
Mulligan/Early Game: Always mulligan for Sludge Slurper, Augmented Elekk, Hagatha's Scheme and Doomsayer. Against Token Druid or Zoolock or such it makes sense to hold a Lightning Storm. Against Rogue or Warrior keep Acidic Swamp Ooze. The deck lacks early game cards so your goal is to clear the board and get some portals going with Portal Keeper, hopefully combined with Augmented Elekk.
Mid Game: You will probably draw some portals already that can help you to contest the board or maybe you get a good Hagatha's Scheme off. Remove your opponents minions or play a proactive card like Portal Overfiend if your opponent allows you to do so until you manage to stabilize with Hagatha the Witch or Walking Fountain. Don't hesitate to play Shudderwock earlier than usual when you don't face a Control Warrior. He's useful for more portals, AoE or repeated value from Swampqueen Hagatha if you know you won't go into fatigue for the second time.
Late Game: Be careful when you get The Storm Bringer as an option from Swampqueen Hagatha. The card is amazing in this deck, but it will go off when playing Shudderwock too. When Shudderwock evolves into a different legendary, the battlecry stops (like with Yogg), so you might not get the Archivist Elysiana trigger. This only applies when you know you might save the Shudderwock for very late turns when you go into fatigue for the second time. You should usually play The Storm Bringer when you have 4+ minions, because otherwise the board wont be threatening enough after. Don't worry about targets for The Storm Bringer, because a lot of 2/2 demons can come out in a single turn.
Control Warrior is definitely beatable after adding Archivist Elysiana to this deck. You also have a good chance against Rogue, because of the Tech cards and the Healing. I am still working on the matchups, stay tuned!
Why some cards aren't in this deck:
The portals don't have immediate impact because they land in your deck, so thats why the rest of the cards are Control Shaman cards. Even tho an aggressive approach based on board control with Sea Giant and such seems fitting, I don't think that'd work out. If you wanna go for that, play a token deck with overload cards.
Bloodlust is a win more card against Aggro and it's only good against Combo or Control decks with little AoE. Because Warrior is the Control King right now and Warrior has Warpath and Brawl it is often a dead card in your hand. In long games you might get a copy of it from Hagatha anyway.
Spirit of the Frog, Wild Pyromancer, Thunderhead and a lot of cheap spells like Zap! or Earth Shock can work great in Shaman, but you just don't have the space in the deck because of the portal synergies.
Hecklebot or Unseen Saboteur can be great against combo decks. Right now the tech cards in this deck are used to deal primarily with Rogue or other Aggro decks. If we see a meta shift after potential Rogue nerfs and Combo decks come back, these become viable options.
A lot of people recommended to use Archivist Elysiana and it really helps your matchup against Warrior. Bloodlust feels like a dead card a lot of times and you might get one copy of it off Hagatha anyway. It is a shift in this deck's win condition, but Archivist Elysiana is a more consistent late game plan. You are playing a Control deck after all.
I feel like one copy of Storm Chaser is enough without Bloodlust. Augmented Elekk is a fun card in this deck, but a lot of times it's just a 3/4 and you can't play it together with a Portal card. One Elekk is still reasonable tho and it keeps the spirit of the deck alive :D. Public Defender is good against Rogue, because they can't deal easily with a 6 HP minion and the Taunt can be worth a lot in that matchup. It's also a decent play against other Aggro decks. To be fair Tar Creeper would be much better if he was still in Standard, but the Public Defender is as good as it gets right now. I consider this a tech card, so if Rogue gets nerfed and you see less Aggro decks overall, feel free to run something else in this slot. Same goes for Acidic Swamp Ooze and Harrison Jones.
