You go back in time to 1v1 your self ..
so here is a fun thought i just had you time travel 1 day back in time to 1v1 your self and both of you are playing your main ( same champ in case if multiple mains )
how do you think you will preform ? i know the first answer that comes into mind is "meh its 50/50" but think about it you and your past self know each other 100% all your secrets and tricks , you have the same thought pattern and same play style and both of you know that so you will try to do something about it , maybe play in unorthodox way but perhaps that what your past self also thought of !
idk but i find this really entertaining to think of , tell me your thoughts and what do you think would happen ? [slayer-pantheon-popcorn]

whichever me landed the first e would win the entire game because of that almost certain first blood.....
