Looking for fun cards for a political / enabling U/R EDH deck

I’m going to be playing with some new playgroups soon and wanted to build a Commander deck that works well as an ice-breaker.

Goal of the deck:

• create interesting and unique games
• help the table “do their thing”
• fit reasonably well into unknown power levels
• avoid the typical chaos cards that can frustrate people
• not rely on its own wincons — more of a facilitator / enabler deck

So the general idea is something adjacent to group hug / political, but without the “random chaos” or “oops I combo-win” angle that some lists drift into. The intention is that the games feel interactive and memorable for everyone at the table. I expect this deck to have a below average winrate.

I’m already fairly happy with the current list, but I’m curious whether there are fun or unusual cards that achieve this kind of gameplay that I'm not be aware of.

Examples of the type of effects I like:

• cards that let opponents choose or create table politics
• cards that help multiple players simultaneously
• cards that enable big plays without immediately ending the game
• cards that work well on their own, not needing additional synergy pieces
• cards that you think are fun

What I’m not looking for:

• heavy chaos (Scrambleverse / Warp World style)
• deterministic combo pieces
• cards that make the game take forever without progressing

If you’ve built/played with something similar and have cards in mind that stand out, I’d love to hear about them.

Thanks for any suggestions.
