How come Loki or Dr. Strange didn't use their Infinity Stones against Thanos??

[Bryan Danielson]

Now that you mention it, I remember in Doctor Strange how the sorcerers freed themselves from time manipulation, so he damn sure wouldn't have been able to do anything to him with most of the gems

Yes.... that is right...... they freed themselves and no where near as powerful at Thanos.

Dude would've broke free of worse.... use his current gems as it seemed per the movie he could use them instantly at will.

As when Loki tried to stab him in the throat and he stopped him or when Starlord was gonna shoot Gamora and he changed the projectile into bubbles to troll him.

And since Doctor Strange uses magic, he could make magic useless by rewriting the laws of the universe

No magic = no spells = no time stone
