Searching for super friends for oops all super friends

Hello all!

I just threw together a deck that has been a bit of a fever dream ever since I started playing around RTR: Super Friends and I am hoping for some ideas and maybe some help.

Now, I know there are actually strong ways to run this deck with proliferate and such, but that is not what I set out to do here. Here, there be shenanigans and silliness abound. I wanted to purposely handcuff myself with Umori, the Collector and their companion ability, limiting myself to STRICTLY lands and planeswalkers: inspired alot by the War of the Spark planewalkers that almost operate like enchantments or artifacts with one static, and one activated ability.

I built this deck purely from my collection, which I have built over several years, and did not realize how many planewalkers have been printed since I took a break! With that in mind, I open the forum to all: tell me about your favorite planewalker, and bonus points if you can make a good argument for why it would be good in a planewalkers only deck!

Thank you for your time, and may you draw lands and spells!
