Maybe it doesn't count, but i queued into evample when playing top 1% rumble (we lost unsurprisingly)

I've played with and against a couple ppl with gc tags (not tourney ones). I beat one guy with a s9 gc tag yesterday in casual 1s

A summer series elite and a rlcs season 4 contender in a private match

Now I play now and then

I often play against friend higher than me like champ2 to gc1 and i once played against a smurf in comp 1s whos name was not a smurf and almost lost to me at 0 seconds
