pretty good with MK, so I can argue for their side.
First of all, and it's a quite obvious one but the MK team has quite the edge in terms of skill, and most likely the more agile of the two, with even MK fodder being able perform crazy Acrobatics feats.
Most the MK team can either see the Bleach team or be able to sense them via vibrations in the air, pressure, etc. Most MK characters are able to sense souls, with some even bring able to interact with them.
Scorpion is a good counter to Toshiro, as he's capable of vaporizing humans, melting stone effortlessly and it's likely >>> naturally occurring fire due to them being from the Nether realm, and Scorpion has experience in fighting against the likes of Sub-Zero and other potent ice users.
As far as the Bleach Team returning from Scorpion's BFR I'm unsure, since it's composed of thousands of layers, layers in this context being spatially separated dimensions. Also is it assumed that the Bleach team is invisible? Because character like Orihime and Uryu aren't from what my memory serves.
Raiden's Clairvoyance is literally him having visions of the distant future, he foresaw Shinnok's forces invading Earthrealm when Raiden was just a kid, pretty sure he'd be able to tell, his precog is like Kenbunshoku Haki where you see the future and everything that unfolds in said future. Shinnok's forces have some members who utilize time Manipulation and other things you can't really "see" and Raiden saw the entire outcome.
