I've just created my first deck, took me a week to make it for free. (need help)

So, I know the basics of playing poxnora, I'm a returning player from times where Grimlic was just being released (oh my) and need some tips about creating competitive deck at least for playing rankeds.
Here:

What does it lack and what is completely unnessesary? Need to mention the little slider, cause I'm currently testing stuff and i like him a lot. he's a nice support and works well with draksar psions.
I'm gonna replace Rite of Empathy (also testing) with second Psy-Sentry. It's a budged deck and I don't want to cost myself with high tier exotics.

 

What is your favorite animal?

 

I think I remember you?

 

Those Psy-Sentries are great, having two of them is pretty amazing as they can play off each other. What kind of a deck are you going for? Are you trying to focus on Psychic damage/amp? Firk tribal? Anything specific in mind?

 

Hi there,

It looks like you are going for a psychic bg which is nice as its cheap and pretty easy to obtain runes. Here is the bg I used to use but don't play firks anymore:

Take out the diplomats for now as they are rather expensive. And one poisonous fumes is ok instead of two. Um, any other questions, feel free to ask. The community here is pretty helpful
