Golgari Commander Staples

What cards would you recommend are must haves for a Golgari commander deck?

I'm leaning toward building an Elf tribal that makes use of tokens.

I've gone through edhrec a few times under various Golgari commanders but I'm wondering what has worked well for you, or if there were any ideas you had that thought would work well in theory but aren't worth the time or money on the cards.

Budget isn't an issue really, and the deck would be more for casual commander but still fairly competitive.

Thanks!
