We did the LT vs strage debunker allready. LT was nowhere near trying realy hard, since if he did he could defeat strange with a blink.
Also, I don't see Strange being at skyfather level with prep. I know Longpig will yell "He took away thor's powers!" but that was only with the help pf the other godheads, who are also highfathers.
If the destroyer armor with the odin sword can's stop them, nothing can.
(obviously something can, but you get the picture.)
YOU did the debunker.
In their first apearence, Lt's charater wasen't fleshed out, and eas even useing magic insted of power cosmic.
And the second one he just basicly made him fight the in-betweener. IT shows strange's powerful, but not that he can stop the LT.
And how did Loki steal all of Stranges artifacts I wonder?
No matter. I still doubt he could take king thor.
