Is Nibiru even worth it right now?

I typically run 2 copies in case I run into combo decks, or at least I used to. These days it feels like getting a Niburu off doesn’t even matter. It’s hard to time it right, since omni-negates are easily accessed before 5 summons. And even when you do trigger it and summon, snake eyes or white forest or whatever have so much recovery that they act like nothing happened and keep comboing.

Is Nib just not worth a slot right now?
