I will write this for the third and last time since it's annoying to repeat the same thing over and over again.
Loki's first move is a Time Travel that is able to affect and rewrite Acausality Type 1, 2 and 4 (which also gives him layered Acausality since he himself is immune to his own Time Travel, btw). Said Time Travel, and all of his Time Haxes in general, are 6-D in nature and allows him to travel across 6 dimensions (4 spatial and 2 temporal), and, just in case an argument is made for that, ignore stuff like Power Nullification since they worked perfectly fine even while all of his abilities were nulled by the technology of the TVA, which is also able to null conceptual time stuff like the Infinity Stones. Said Time Travel allowed him to travel to and rewrite a place that not only had the previously mentioned Acausality, but that was also temporally destroyed and didn't exist anymore across all time and space. Basically, even if a character have Acausality, the match would already be over before it starts.
And just to say, passives would also have a hard time working on him. When the Temporal Loom exploded, the entire Multiverse, including the TVA, was passively erased across all time and space, and yet Loki's Time Travel was able to bypass said passive destruction since it had a hard time reaching him while he was Time Slipping, and Loki at the end of the series was even able to undo said destruction across all time and space, despite said thing already having happened and the place he was rewriting not existing anymore. So, overall, his Time Travel is busted.
And with this I wont touch this again since I am on a break from this wiki and I am pretty sure I already explained at the very least the Time Travel part before in this very thread, so I will dip out once again.
