How Strong Is Mr Mxyzptlk

Mr Mxyzptlk is already able to hold creation aka DC multiverse in his own hand like an 2D disc

Making him above realms such as the multiverse,the sphere of the gods which is stated to be platonic and it's an metaphysical plane if existance already making it 6D-7D Feat Since it includes the DC Multiverse,Gods Sphere,Limbo,Bleed etc etc expect the sixty dimension

Mr Mxyzptlk along with bat mite is able to destroy the DC infinite Multiverse and timelines and then restore it like nothing

He is also able to turn Colors in the comics into drafts literally erasing colors out of existance

Break the fourth Wall,Hop Through Panels Etc Etc

He is also able to open an portal through the six Dimension aka the monitor sphere although it takes a lot of power but still

Overall Mr Mxyzptlk would in my opinion scale to Outer 9D with Irrelevant Speed
