Premature and Call in chaos turbo

I'm a little surprised these cards aren't run at all in any lists. I understand the anti synergy with the chaos monsters removing the graveyard but you can also reborn those if the opponent ever kills them.

I'm sure people have done the work and figured out that it's not worth it to run them but it still doesn't sit right with me. They're like the only 2 powerhouse cards the deck doesn't run and special summoning is so powerful in goat. Idk I'm probably going to have to test this myself
