Can we get a clear outline of how many Event Missions there are?

It would be nice if there was somewhere that would outline how many missions there were. I completed the final mission, and the 'intro' mission (30 games). In the past, there have been timed missions which pop up every other week... whereas this event it seems that once you're completed, there's nothing left?

Essentially, it would be nice to know so we can spend our tokens if we're all done.
