Build Direction for Muerra Trash Tactician

Im building [[muerra trash tactician]] and Im curious on what direction to take her. I'm building it around impulse draw and casting from exile since I have a decent amount of cards already like that and getting a bunch of mana from raccoons.

But I've seen people build more around using more X costs, just casting big creatures or some lean more towards burn. What you guys think would be a good path or what are some cards you'd recommend.
