extra champs in tft

I noticed in the beginning someone was level 4 and had 6 champs on the board, so I asked them, and of course, the said they have woodlands and I needed to learn to count. Then I noticed the rest of the game a Maokai and Ivern just chilling in the same 2 spots. I looked at other people's boards and some were normal, while others had a random Ivern on the board. My laptop couldn't screenshot those for some reason it was just a black screen, so I took a few pictures on my phone. I'm not sure how to upload them on here using my phone though so I can show you what I mean.
