Nowadays, if it's in the squad builder, it's fair game.
^^^^^^ This.
For whatever reason FFG insist on "Previewing" the cards many months in advance, though I would probably call it premature viewing as after the months go by the excitement for the actual cards wanes to just a dribble by the time you can actually have a legitimate copy of the card (Even more so for us "Outer Rim" Countries, we don't even have the new core set yet!)
Best to make the most of it while its shiny and new, even if you cant play it in a tournament for several months.
What puzzles me on it is that they often spoil the most dramatic cards early.
I mean, I'm happy enough knowing that the T-70 is coming. But they spoil the X-wing fix in the very first spoiler article? Just imagine if they'd kept it till closer to time. ![]()
