Hextech - Some people have been building it since he came out - works
Guinsoo - no pls - doesn't work
Nashor's Tooth - You'd need quite a bit AP to make it better than Wit's End for example - doubt it'll be really worth it
Liandry - Your main damage source (Q) deals both, physical and magical damage so it might work. I don't really think it's a good item though
Sorc boots are kinda optional because you need some defensive stats for your ultimate to be actually effective
IN OTHER WORDS
While it might work (with a bit different item build - Iceborn/Trinity + Hextech + Wit's) I don't really think it is really optimal for Skarner because he needs mobility and survivability to be useful due to being melee and having his ultimate.
