The meta has been missing on shamans so I decided to fix it. The deck is incredibly strong but does struggle against druids and paladins. Plague of murlocs and zentimo plus hex allow you to turn priest's and embiggen druid's strong minions into a pile of garbage. The deck has multiple board clearing spells that synergise very well with shamans new weapon and phaoris.
Shaman's galakround offers free minions that help you keep control over the board in the early game while they can be ressumoned with shudderwock.
Hagatha acts both as a board clearing spell while also giving you value out of her hero power that can be later used with the weapon and phaoris.
Do make sure to try the deck if you got the cards. Upvote the deck to let me know if I should bother with compiling a detailed guide for you.
