I want to have all Half Life 2 cards.
At this moment I have 4 cards from Half Life 2, but two the same. So I can trade some of my Portal 2 cards (but not all), to get rest of Half Life 2 cards.
Portal 2 cards:
Chell,
Destruction,
Finale,
GlaDOS,
Intro,
Mannequin,
Underground
From Half Life 2 cards that I have now is Gordon and Alyx, Trouble Underground (and 2 Bring the fight to them, but I can trade only one)
