In what way would that be FIFA. Im not too familiar with the game but i know my way around it

I don't know my copyrights but i'm pretty sure you can't copyright strike someone for that concept as im sure it has happend before.

Fantasy makes it so whenever theres a big turnament you can create a custom team with the players participating. You get a budget and diffrent players have diffrent values. So fx Scream costs more than Nivera because scream has better stats. There are also categorys like. Headshot master (Highest headshot procent) and even more.
Would love to see that in valorant too.
