its either urgot rework or yasuo new skin
Well on Surrender@20 it says it's some sort of kickoff for the LLN. So don't get your hopes up just yet.
Chem-tech Tryndamere or Urgot rework (probably the latter).
Not a new champ.
Rakan+Xayah were released on April 19th.
The GIF has a note saying May 29th.
They wouldn't release a new champion one month after the last one.
iT ALMOST LOOKS LIKE IT COULD BE ANEW urgot face (caps but i was too lazy to retype it) (In hindsight retyping woulda been quicker)
it looks like 
idk it might be some weird urgot teaser
doubt it's demonblade yasuo, they wouldn't tease it without teasing angelblade riven too
looks like mordekaiser to me tbh
According to the leaked Urgot rework his ult made him immobile and has a metal hook that's an assured kill, or whatever the guy had said.. :p I think its urgot
Return of the battlecasts? Battlecast mordekaiser confirmed?
I honestly feel like it looks like Leona's shield, but otherwise it's Urgot's face
Looks more like a skin, we have yet to see any champion with that kind of style in base. The metal just seems off to me.
New image and new sentence which basically means "Only one will rise": https://2.bp.blogspot.com/-44ca9eDtQnc/WSo9tgwxiZI/AAAAAAABDrU/8njhFp5tw2kHvqZ2XUs7mzxys12r6tO4ACLcB/s1600/18698082_1468238059899900_8266380480732236547_n.jpg
Since this looks a lot like Riven's blade we can assume the teasers are Demonblade Yasuoa nd Angelblade Riven.
Can't wait for a certain rule to apply :3
