This has also been occurring for my friend. He has enough Calico games played last month, and enough Graves games this month. But he has not appeared on either leaderboard. Maybe there's a hidden MMR requirement? I appear on the board for Victor and Rem without issue the day after I hit 20 games within a month for them and am currently ranked Ascendant 4. He is Oracle 3 and has not appeared on the Graves board despite having well over 20 games on her. The Graves board only listed round 600 or so players last we looked so he should have room to appear.
