So what do these cards actually do and how do I activate them?

So I opened all these packs and they gave me really OP bonuses and upgraded weapons. I exit out and can't find them anywhere. Where are they and what do they do? Can you only have a certain amount active at the same time. Thanks.

The cards are modifiers for score attack and expedition modes. You cannot use them in the story. Score Attack lets you play sections of the game against the clock and the cards are useful for getting high scores.

The cards are for the games under Expedition Mode. They can be used to enhance your scoring under Score Attack, Chapter Replay, Chapter Replay Elite, Endurance Single Player & Coop, Remnant Resistance (player created scenarios), Cold Darkness, & Lara's Nightmare. They cannot be used in the main campaign.
If you are going for 100% Achievements (through Steam of course) you will have to play Score Attack & Chapter Replay Elite to achieve the Golden Child & this is where you can use them to enhance your final score.
The cards with a green "percentage" are foil cards and enhance your final score. The cards with a red "percentage" are the detraction cards and reduce your final score.
Most of the Expedition modes you may only use 5 cards. In the Coop mode of Endurance, you may only use 2 cards each.
Please note that you can only keep a certain amount of cards in your inventory. To access these cards, go into Expedition mode, pull up Score Attach (doesn't matter which section you choose), then hit continue & it brings you to the cards page. Click on the first empty slot & that shows you just about every card you have. Please note that some of the cards are not in this inventory as they can only be used under certain conditions such as Remnant Resistance.

Not OP but thanks for the answers as I was also curious, really glad the cards aren't for story mode.

I was just going to ask the same question about the cards. I'm glad someone beat me to it and answers were giving. Thanks! To bad the cards aren't for story more tho. I feel like the cards are a huge waste now.
