Potential TFT bug?

Hi Riot,

My friend and I both encountered almost like impossible to win condition for TFT in different games. The 1st place players both have 5 3-star units, and the champion they used are too similar to be a coincidence. They all had 3-star Lucian/ Pyke/ Graves/ Trist and potentially a GP.

Did anyone else also encountrer such situation? I really would love to post pictures here but I don't know how.
