How do i know if it's safe to sell a card?

How do i know if it's safe to sell a card (that he's not included as part of a collection)? There's no easy way of checking this, as far as I can tell.


Is this something I should spend time checking and caring about? Or are collections just pointless?

They added it in 3.0...you have to check the missions in 2.0, take a glance at all of them if you can, or notice maybe if the avg. 7 day price is really high? might be a good time to sell...

There are many other considerations before buying & selling, too many to list, probably.
