Make a new account, grind to get new players and rank them (it takes a while), while trying to somehow alternate between accounts, all that to just play unranked seems a bit too grindy for a gamemode that's supposed to be casual.
While I agree with the post and all the replies, I believe unranked could be a bit more flexible for top-tier players, since he replied that he can only face 50 stars and above players which is 1% of the whole FC Champ rank.
I know it requires a bit of messing around but if the OP wants to play unranked games right now, until the logic changes, it's either a new account or playing friendlies in your LVL league or with in-game friends.
