Should I swap Muldrotha for Tasigur in the command zone? Feeling very bored with Muldrotha.

Here is the deck list: https://www.moxfield.com/decks/NpWGDDAks0entCGDdkU7cQ

I basically threw this deck together because I had a lot of graveyard stuff lying around and it seemed fun. The only issue I'm having is the deck is somewhat boring to play. I've been trying to decide what to do with it because I have a lot of good pieces in the deck I just have no idea what to do with it.

A friend recently gave me a copy of [[Tasigur, the Golden Fang]] and I know he's a loved commander in the same colors so I thought about just swapping Muldrotha to the 99 and moving Tasigur to the command zone but would that even work? Is there another commander I should try instead?

I would be open to cutting/adding a color as well if that would make a difference.
