What commanders can you recommend similar to Sefris?

Hello!

I have an average 100€ budget [[Sefris, of the Hidden Ways]] commander deck which I'm thinking on taking apart since my usual playgroups are hating that the deck is taking long turns since I have to explain to them how dungeons work. Obviously I'm shortcutting while I'm doing game actions, however, since it's a mechanic they aren't used to, it's being a struggle for them, to the point that the deck is "pseudo-banned" for taking too long.

Any recommendation on something similar to dungeons/initiative without being that time-monopolizing? I would like to reutilize a lot from the deck, but since initiative is too specific, I would probably try to stick at least to Esper (Orzhov/Dimir might be good as well)

There's the deck if you want to know what I'm talking about. https://moxfield.com/decks/m1n-zHWw7Uy-9r0xCbE2xQ
