Another thing is that this may not be necessarily your traditional stax, because I want to prioritize having as many enchantments or creatures as possible, in order to be able to counter anything I want. I'll try to put more enchantments/creatures primarily, depending on what kind of stuff I need. I'll definitely put an update on this when I actually decide to update it.

I decided to update the deck, and I put in a post. Let me know what you all think about the changes. I really appreciate your feedback!

I sometimes wonder if Spurnmage Advocate could ever find a home, but seeing this deck makes me wonder if it might fit in here as a deterrent of attackers that can be sacrificed to counter something if you're desperate, it's only W to cast and the downside interacts incredibly well with your Stax effects. For example, if you have Rule of Law out, you can usually give people things like Ponder, as long as they are Sorceries they are almost worthless, if you have an effect that makes lands enter tapped you can give them Fetchlands with a smile. Other Stax/Hatebears let you pick other cards as situationally bad. Another upside of Rule of Law + Advocate is the opponent can't flood the board easily, making the deterrent more effective over time. This advocate is also good with your Drumbellower, especially since it doesn't use extra mana to activate it's ability.

Have you considered tossing Zur the Enchanter in here? You have quite a few small enchantments (18? I run Zur in a deck that can find about 12 cards, and he's an all-star in there), so if you resolve him it could feel pretty good.

Do people play a lot of interaction in your meta? If so I really love having Wandering Archaic  ^Flip out with Rule of Law, it makes it interaction a lot worse vs you, and much better vs most of your opponents.

I'm going to have to fiddle around with your list at some point, I've wondered how effective a competitive deck this Ertai would make, the effect is very strong, and the colours are strong enough, I guess Zur just caught my eye first and I built that way back, and cEDH lists are pricey! Anyways, cool deck idea, hopefully you can keep it updated/polish it up as you notice issues.

Thanks, DreadKhan. Those are some really good suggestions for sure. I'm not sure exactly sure why I didn't consider putting in Zur before, considering he can fish out enchantments. Wandering Archaic would be actually be pretty good as well, because my friends that I play with do indeed run a lot of interaction. Spurnmage advocate is definitely something I can try fitting into my deck, as it seems to do pretty well with my rule of law stax effects indeed, and the fact that I can just give them back cards that are tapped or useless against my stax. Removal on a stick seems pretty useful as well, so that basically synergizes with my counterspell on a stick as well.
