What are your thoughts regarding future additions to the timeless format?

Already b4 Chrome Mox was added to Timeless, Bx Combo Decks had reached a pace, that was near unbeatable for controlling decks, currently control (and even slower midrange decks) are completly out of the meta.
Imo at least Force of Negation, if not Force of Negation + Force of Will are required to counteract the speed of the formats combodecks and establish a somewhat level playing field.

I've added some of my initial suggestions below:

Interaction:
Force of Negation
Force of Will
Force of Despair

Wishes: (enable different combos decks)
Burning Wish
Living Wish

Red Rituals: (enable Storm Decks)
Desperate Ritual
Pyretic Ritual
Rite of Flame

The Rest:
Urza's Saga (What could possibly go wrong?)
Preordain (Ponder is most likely a step too far)
Mox Opal (If Modern is ready for it, Timeless is aswell)
