The minion lineup looks about right, but the spell line up can use some real changes. Devolve and Totemic Smash aren't that helpful for what you're trying to get to. They're removal options, when realistically, you're trying to close the game up by around turn 5-6.
Considering you're swarming the board, running Storm's Wrath is far more useful, and gives you a real comeback off of goliath, while also synergising well with your 1 drop cards. Also Serpentshrine Portal is an incredibly flexible card that can be used as tempo, removal, and game ending damage.
I'd also probably recommend cutting a copy of Bloodlust, replacing it with Vessina. The reduced mana cost makes her more flexible, and will clog your hand up less. And can still just be played for tempo.
Another change that might be worth considering is I don't know how good Trick Totem actually is. Obviously it's great for the curve, but Flametongue Totem is a very consistent totem that has won me a lot of games back in AoO for me.
The last cards that are worth considering, but I don't know how to fit them in would be Instructor Fireheart as a flexible game ender, that can basically be the god tier topdeck, Flamewreathed Faceless as a huge stat swing on 4, that still doesn't lock you out of your strong 3 drops the turn after, and Cumulo-Maximus as a tempo swing and potential game ender.
Hope this gives you some ideas, and helps a bit. I wish you luck with your tinkering.
If you want a strong Totem-focused deck, I'd recommend going either Even or Odd Shaman. Odd Shaman can summon multiple Spell Damage totems to deal fatal blows with spells, Even Shaman is better at filling the board with Totems and get more use out of totem buff spells. Both will probably perform better than a Totem Shaman without an improved hero power.
If you still want to play just Totem Shaman, I'd first remove Trick Totem, because your opponent will be efficient enough at disrupting your gameplan. It's too much of a gamble to hope for spells that won't backfire hard. Flametongue Totem is better.
Crawver has made some good suggestions already. Vessina is a bit more flexible than Bloodlust as a finisher, and Storm's Wrath is a good way to make an early board more threatening, especially with Tunnel Trogg.
Thank you guys for the help. I'm playing the deck still with 2x Devolve. It wins me games again early aggro aggression and big taunts. I added 2x Storm's Wrath. This card is really amazing, because you often have a wide board and you can push very fast with it. Trick Totem is very good too. It wins me more games then loosing and it´s with 2 mana very cheap and awesome, if you play it on curve. So i reached 62% WR and i climb very fast. The only problem is priest.
I've always seen Cryostasis in even lists but was never sure what its there for how do you use it?
also does anyone know the interaction between Zentimo and Totemic Reflection? (does it copy the totems and give them buffs or does it buff and then copy?) (if its the first does that mean that mean you can generate a 7 minion board if you have 3 totems on turn 6 and then wack em with the zentimo reflection?)
also here's my list that i cooked up and had success with yesterday:
Although Explosive Evolution looks kinda similar to Cryostasis on its face, there is a hugely important difference. Explosive Evolution gets rid of the totem tag, which is incredibly valuable in even shaman. Sure you can get a random 4 drop really easily, but that 4 drop doesn't get buffed +4/+2 on your notetaker turn and it doesn't get copied by Splitting Axe. For these reasons, its vastly inferior.
