I'm not 100% familiar with all of them, but Foolish Burial could seem a little helpful to you here.
Maybe Gold Sarcophagus, MAYBE.
Definitely add 2 Stardust because its a staple in ANY deck, and maybe Thought Ruler Archfiend. They help as much as any other staple. Maybe use xyzs, when your back is against the wall, they come in real handy!
