To play in tournaments with my duo

I want to play in online tourneys together with my duo, hes my duo that ive played with most of the time, we're both 13 and we both really want to try tournaments, we're iron 3 but i peaked bronze 2, we're somewhat OK at valorant, we're better than average joes in the depth of low elo,
we play sg and hong kong servers and if we were thrown into gold games we could kind of hold our own
