I got this list from DeQuan Watson. Check out the video here:

This deck aims to play a lot of cheap creatures and use cards like Conclave Mentor, Grakmaw, and Swarm Shambler to take advantage of those counters and leverage them into more counters or additional creatures. I would consider this to be an aggro deck, but some of the interactions definitely give it a bit of a combo feel.
This looks like a fun deck to start to explore the format. The interactions look to be competitive enough, and the ability to snowball advantages in creature decks is usually pretty fun. I think this is worth playing in Bo1 to start exploring the format, and potentially worth porting over to Bo3, maybe with an additional land or two, if the deck feels strong enough
