Your deck seems to be based around good-stuff strategy, with no clear synergy or theme to the deck. In my experience goodstuff decks have a tendency to get old faster then themed decks, assuming you enjoy that theme. Also without the cards working together to build a large advantage, your individual cards need to work harder to win you the game.
I am not up to date on the prices of some of the cards. But here are some additions I would make. It seems you have a light token theme, so we can build on that while swapping some weaker control cards with more flexible options. I apologize in advance if it looks like I am tearing your deck apart. These are some opinions and feel free to use as many, or none, of them you like.
You need to add in at least 5-8 MORE creatures. 20 creatures in a deck like this looks terribly light, especially when your Commander wants other creatures in play to pump. Take a close look at Puppeteer Clique and Woodfall Primus, as persist works well with your Commander.
Someone with a Ghave deck will be along to throw out some more token support. I play more reanimation in my GWB deck, and not much token support.
Lastly, I just noticed all of your Pro-Blue, Pro-Black creatures as defense against Etrata, however adding some good instant speed removal should mitigate the amount of hits you take from Etrata. Just make sure you leave removal mana open after Etrata enters the battlefield and threaten a removal if she swings your way. That shoudl make your deck much more versitile than playing mediocre creatures with Pro-Colors. There may be some better options in Hexproof creatures, but I am not sure.
Or add some swords of X & Y with Pro Blue and Pro Black for much greater benefit. Not budget, I know. Sword of Body and Mind seems good for you, and you even want the wolf token; its not horribly expensive. Sword of Truth and Justice and Sword of Sinew and Steel are coming soon. Get that trade binder ready...
