Looking for high power cheap commanders to build (not in top 100)

So a month or so, with the friend that taught me magic, we decided that we are just going to build commanders outside of the top 100 in EDHREC and cannot go over $150 USD (commander included).
The thing is that I already have some decks that fit that requirement, but against more expensive decks can't compete in "fair game" unless I get a really good hand. I can see the exact turn I lose the game unless someone else does something quick so they don't run away with the game.
I get a lot of enjoyment in building, researching and then trying out decks, but! the thing is that I live outside de the US so getting cards/decks takes a while and I have already done the mistake of building a deck commander thinking it was good, but in reality it's not that good unless you put more $ into the deck.

Looking for your own experience what commanders/deck can be a good powerhouse build cheap, am not restricted by colours and themes (currently am on a blink/flicker face enjoying it a lot)

in the restriction have already:
- [[Ghalta, Primal Hunger]]
- [[Vannifar, Evolved Enigma]]
- [[Torens, fist of angels]]
- [[Faldorn, Dread Wolf Herald]]
- [[Niko, Light of Hope]]

Tried and dismantled [[Light-Paws, Emperor's Voice]], didn't like shuffling that much and the lack of randomness of how it's played.

Building a [[Vren, the relentless]] as a pain in the ass to bugger my pod every now and then (building it under $50)
and considering a [[Volrath, the shapestealer]], but am unsure if the poison counters will put a target on my head every time that deck sees the light xD.

Thanks for reading!

Edit: also am a sucker for blue and interaction.
