mtg when a creature dies draw a card High-Society Hunter (Foundations Promos) o:"this creature enters" or o:die)

Then Muldrotha, the Gravetide is the top commander for you

One card Im hype to include is Gix, Yawgmoth Praetor

Abilities that trigger when a card is discarded will still trigger

While not for every deck, if attacking is a part of your strategy or you simply want to turn that obnoxious Ulamog, the Infinite Gyre or Blightsteel Colossus back on its owner, consider taking Bribery for a spin and checking out the work it can do for yourself

You can play any color pairings and any style you like

Birthing Pod is actually banned in the Modern format, and has been known to do some fairly disgusting things at Commander tables to boot
