with the proportional strength and speed of a squirrel 1-A and Immeasurable, well, squirrels are really crazy
Anyway, the profile is great, but I'm not convinced by a couple of things.
Deadpool's guide should be counted as Information Analysis, for the cards don't analyze the opponent, they are just source of knowledge. It would be like saying I myself have IA because I can check Wikipedia on my phone at any time.
I'm not entirely convinced of the way her tiering is set to work. I don't really see reason for the Varies, as nothing there confirms she herself is empowered by squirrels, Doom was talking about the absence of her allies that could gang up on him like the last time.
She defeated Thanos while having only Tippy-Toe with her, which should make as strong as the time she lost to Doom, since she once again had only one squirrel.
To me, it would make much more sense to just make her 3-A, while keeping all the scans of her High 8-C rating, but just for support, since she clearly stomps all those other characters anyway.
1-A via Summoning should work, but I don't like scaling Doom's technology to Galactus and the Beyonder, because while it would be comic-chronologically correct, those devices are not referenced in the story itself, and this kind of nebulous, speculative scaling is stretching matters a little to much, in my opinion.
