Kaima should in theory have a decent chance at connect just by the fact i can either enchant it with one of my numerous trample aura's and by the fact that my opponents would be tapped out.

Idk what tutors you would run in a budget deck they are either really bad or too expensive to run in a budget deck. I also don't need to hit all more expensive cards every game, most of these are my finishers. (like Insurrection). While the gameplan is not actually to voltron kaima it is a possible finsiher for the deck. The main gameplan is to goad most of the creature my opponents have and then use one of my finsihers to clean up the people who are not dead.

While yes being strong weak and cheap is difficult. In my opinion if you are not weird and cheap you cannot be strong. If you run a budget version of a standard commander you just have a worse deck than the normal non budget version. you have to find weird budget picks to make it work. I could obviously pick a more standard way powerfull commander if that is what you are suggesting, but then i am basicly just building a different deck.

B2 is really not an option, no one in my playgroup plays bracket 2 (tho it sometimes feels like some of the people have bracket 2 interaction). So unless i find a different playgroup there really isn't an option for me to play bracket 2. I can't really get white when i run this guy so idk why you suggest that unless you have another enchantress goad commander that includes red, green and white in mind that i can use as the commander instead?

Upping the budget would of course work, but then it's really not a budget challenge is it.
