Fun is functional to that, but there must be a minimum level of effectiveness.
I don't care to play a deck that is purely fun, but not enough effective: it would give me no satisfaction.
And my effectiveness would not improve in an environment with no rewards whatsoever (basically it wouldn't help my collection, which is the source of my effectiveness).
I play for satisfaction.
