Well for one, this is flash with the entire speed force absorbed into him. A Omniversal power....
Flash could by all means just bring about absolute 0, or he could vibrate him self to such an extent that his very presence rips apart the universe/multiverse, retcons everyone etc..
Thats why I said he has full access to using the speedforce for whatever esoteric/creative abilities he wants
I assume that this fight is meant to be Flash stacking the deck with everything possible that he can and doing everything in his playbook to win. So off the top of my head he has matter manipulation as shown by his ability to create a costume out of pure speedforce and I believe Wally used it to make braces for his legs when he broke them and he pushed ftl easily IIRC. Speed force flash is a god over any and all energy in theory. All kinetic/potential energy is at his disposal to manipulate at will given his capacity to speedsteal/give. Omniblasts don't work considering he can jump into a dimension that as far as I'm aware a single scientist the speedsters and zoom have gotten into.
Furthermore Flash has taken the speed of an entire planet of speedsters during the cosmic race in Flash: the Human Race. There is nothing to suggest that he could not expand this capacity and draw the kinetic energy of a larger area say a solar system/galaxy/universe. It's not really a overly used power but from what has been seen there isn't really an upper limit that I've seen. Beyond that Flash becoming one with the speedforce exponentially increases his capacity and with every step Barry takes he's only increasing it.
Honestly this is why I was hoping for a post reboot flash nerf but flashpoint made it clear that his capacity will reach pre-flashpoint levels unless a retcon occurs that Barry will not be able to remember the events of flashpoint/alternate timelines.
All this mind you is mostly putting together and extrapolating his capabilities from their and all hypothetical. However that said if I were to have the flashes abilities/decided to write him on full capability only on using what was shown he'd easily be one of the most powerful characters in existence.
Flash takes it imo but mostly because stips are highly stacked in his favor, i don't see how team 2 could do anything to tag him, psychics don't work on a high level flash his thought process just moves too quick and confuses the hell out of them and he can hit repeatedly with planet busting force if not greater, can't be bfr'd cause he'll just speedforce jump back and he has quite a few options on how to deal with anyone on team 2. Basically Odin going completely intangible/spirit form is the only thing that would get in his way and even then it would be a draw. Flash would never tire and I don't think there would be anything odin could do to tag him even with omnidirectional blasts because flash would again dimension hop/ timetravel to dodge.
taking Flash's capabilities to the max and using every feat he's ever used speedforce for he becomes a stupidly powerful character and I mean stupid. Honestly I don't know what writers were thinking when the started handing him his speedforce abilities... I can just imagine
"We'll give him the ability to control/steal/give kinetic energy... I can't possibly see how something like that can be abused. Oh and to top it off lets give him an infinitely growing powersource that grows with every step he takes... Then lets prove that a Flash can absorb it in its entirety."
If he continually accelerated and his acceleration= level of growth of the speedforce which, considering he split the universe into 3 distinct timelines by just running fast... I don't really think its beyond the realm of possibility... Splitting the timeline of the universe even though it was manipulated is higher on the scale than busting a few thousand galaxies in my book because it was still Barry's power which directly split the universe... into 3 timelines. Haven't seen Odin Surfer or Thanos do anything on that scale... with all of their abilities sans items like IG or HotU.
