Gravitational Anomaly [Single]

I'm not quite sure how good this card will be (considering it's based off of Zero Gravity), so some pre-YCMing feedback would be nice.

Gravitational Anomaly
Trap Card

Select 1 monster you control; change the battle positions of all face-up monsters on the field, except the selected monster. The selected monster gains 200 ATK for every battle position changed, until your next End Phase.

(Any OCG corrections are definitely appreciated)

Target 1 monster you control; chang the battle position of all other face-up monsters on the field. The target gains 200 ATK x every battle position changed (until your next End Phase).

Well now, tbh, I feel it is a really good idea, something new (at least to me, lol) and a lot of cards would like this... I can't say for certain if its OP'd or not; mainly because it changed all monsters except one... that effect both simple, but also a little over-the-top...
But with where it is now, its still a good card... 8.5/10

Haha, thanks, both for the OCG shenanigans and the feedback.

and bumps.

Don't worry, this is certainly not over the top or overpowered.

Think it should only be til Standby Phase, but other than that simple little card for offence and defence.

OCG looks weird on the x battle positions changed bit; but not sure how to word it.
