Not sure if the rank will actually affect future events or if it's just some stupid moniker to put on your prof. From the info that pops up at app start-up:

"Rank is persistent! Keep your rank throughout every episode"

"Rank battke bonus! Rank bonus used in BOSS and CAMPAIGN episode battles"

So.. yes, rank will carry and will boost your deck power in some way (on boss and campaign events).
