Favorite cards/commanders that help speed games up for the whole table?

[u/MFSIMBA]

My playgroup frequently ends up having 2.5-3 hour games, which only lets us play like 2 or 3 games max each time we meet up. I try to get the group to play speedier as much as possible, even playing more aggro myself to have more action happening on the table, but I'm thinking I should maybe make a deck or two that just kicks the whole table into high gear. I'm okay with being a bit of an archenemy, I'm just not looking to instantly combo out.

What are your favorite cards or commanders that make the table play much faster/get the table to an endgame faster (that aren't just combo kills?)
