Trying to roleplay as a merchant in a casual non-EDH deck themed around setting up a "shop" with Share the Spoils where other players can trade for cards. Need recommendations!

Hey! Building a 60 card deck for multiplayer of around 4 people. Have about 50 cards picked out right now at https://tappedout.net/mtg-decks/merchant-roleplay-deck-wip/.

Deck is based around [[Share the Spoils]] with cards like [[Tempting Contract]] and [[Blatant Thievery]] being there as a theme for a shady market. My thought process is my "shop" would be the exiled cards connected to the 1-4 Share the Spoils out on the field. I'd act like I'm trying to sell those cards away and say stuff like "We got a special on goblin cards today!" or "I found an Archon of Cruelty during my travels, on sale now!"

​

Some more powerful cards included like [[Wild-Magic Sorcerer]] I am giving a pass on because it's strong and I just really like [[Urza, Academy Headmaster]] so he gets a pass.

I would really like card recommendations so I can fully embrace the merchant roleplay or other cards to help strengthen my deck! I do want to prioritize making this deck fun to play against above all else, however.

(Sorry I know Thursday weekly post is in 5 hours but I am going to be travelling most of the day and probably won't have internet. Besides... I think I get way better answers this way haha. If mods want to take this down I'm okay with that.)
