Would it be ok to host a 1 v 1 contest for 2 other contestants to compete in?

[I Hate Snatch Steal]

I have some card ideas that I'd find it amusing see in a 1 v 1 contest, but I don't know enough about the relevant deck type to make up or judge an entry. Thus would it be ok for me to host a 1 v 1 contest with the requirement already chosen for 2 others?

Eh, not for the Leaderboard. For a regular 1v1, nothing against it iirc.
