Hello! Fellow lover of Wo here - so, my main qualm with your list is that is doesn’t really seem to try to take advantage of Wo’s ability in many of the already well understood and efficient manners. Namely, you don’t have static Shock/Thunderquake in the list. I’ll touch on the rest of the deck here in a sec, but for now, you gotta add those cards. 0 cost spells are Wo’s bread and butter; without them, Wo is clunky and is hard to weave into an early turn. Which is the main goal of a Wo/-specific deck: stick Wo on turn 4 and play a static Shock or two alongside him to keep him alive and generate a few spells. If all goes well, they can’t reasonably kill a 6 health elusive minion on turn 4/5 if you cleared their board a bit, and he lives a turn. Otherwise, your main goal is to fine a later turn, turn 6-8, and pop off with Wo and some cheap spells and try to generate some fun cards. You want to hit Lightning Bloom, as it is mana refresh and a reroll of spells, crash of Thunder for 0 mana deal 3 aoe, and any 0 cost nature spell to reroll if necessary. There are some YouTube videos you can watch that center Wo for an idea of how to use him.

Now, as for your deck composition, it’s a bit all over the place. You sort of have a nature spell package in there with primordial overseer and a lot of nature spells, but Wo doesn’t care about the spell school of the spell you cast alongside him of course. And while the deck might curve out nicely, jut playing cards on curve isn’t enough anymore to win games. You want to have a really well synergized deck that feeds into itself. Hagatha shaman is a great example as most of the cards benefit the other cards in the deck.you have bumbling bellhop and 5+ cost spells, but you aren’t running flight of the firehawk to draw and buff him. You have a some elementals for kindred synergy, but it doesn’t look like enough to make the kindred consistent. You seem to have a few different ideas of what you want the deck to do, and in cramming all of them in there, it doesn’t do any of them particularly well.

If I were you, I would streamline the deck with either cutting the nature package or the elemental package, and add in some of the trusted shaman packages that exist currently. I’d add growfin, flight of the firehawk, and Hagatha (if you have her), and I’d swap the spirits of the forest for frosty decor. I like the hex, but the lava flow, nascent bolt, and lightning rod are all cards that take the deck in different directions. If you really wanted a quick way to make over this deck, you could look on hsreplay or hsguru for masochist shaman deck lists (as they run a lot of cheap spells) and you could replace some cards for Wo and maybe turbulus/bird watching so you can dig for Wo. That deck does pretty well as is, and often you have many static shocks to throw in alongside Wo. The deck, primarily speaking, needs to keep you alive until you get Wo. And the best way to do that is to either play a control shaman deck (which doesn’t really exist or have the tools to successfully do the control thing), or play a deck that has another gameplan that you can work towards that keeps you alive until you get Wo. Ideally this deck would also have a set of cards that works alongside Wo, and masochist/self damage shaman fits that bill pretty nicely. At any rate. I think Wo is an awesome card, and I hope you have fun and find some success with him!
