i am new to the forums, so forgive me if this has been addressed, but is there any plans or is there somewhere, where all of the existing cards that are out for Legion can be looked at?

I always get ideas for armys but I have to wait until I get back to my collection before I can look at the data on the cards to see if my ideas will work.

There are apps and websites you can use for free i.e. Battlescribe app or the tabletop admiral website. These sites and apps include the card data and they automaticly calculate your army lists.

Table Top Admiral has a card archive

Google star wars legion wiki. That's the best resource I've seen. It's kept pretty up to date as well (as wikis usually are).

Here's one http://legion.fabpsb.net/extensions.php?lng=en#SWL13

As arnoldrew said, the Legion Wiki. It's my go-to source for stuff like this.

Thanks for the options, this will help me plus it will be helpful when explaining the game to others.
