Yeah that works for me, new verison. Though given its now a one time would a buff to all monsters like its now written be suitable? If not than the level 4 or lower change works as well.

Card Name: Rule of One
Trap Type: Normal
Effect: Change the levels of all monsters on the field to level 1

quick question are we sharing one field and one graveyard?

Considering we're taking cues from the video games, I'm pretty darn sure that we do.

@Tojin your turn to post in collab when you have a chance.

Name: Nova Sanctuary
Trap type: Continuous
Effect: While this card is on the field, this card's name becomes "The Sanctuary in the Sky". Once per turn, you can pay 1000 Life Points; Special Summon one "Nova" monster from your deck. If you control a 'Parshath' monster, you can Special Summon one 'Nova' Fairy-type monster from your Graveyard instead.

Swap around the grave and deck effects. It seems a little illogical to give the stronger effect first.
