Card System Introduction
Personal experience of card system. Results from google are a bit outdated because it shows the old card system. For example,OLD SYSTEM: combining 3 normal poring card will give you 1 silver poring card. NEW SYSTEM: The card system has been revamped into combining 5 different cards to get 1 random card of higher rank.
Obtained cards can be equipped into the "Character Card Slot" in the character info window.As the character levels, the locked card slots will open in order And if you equip cards intothese slots,the card's power will be activated.
Level 01 - 1 slot opened.
Level 10 - 2 slot opened.
Level 20 - 3 slot opened.
Level 30 - 4 slot opened.
Level 40 - 5 slot opened.
Once equipped a card cannot be removed. However, you can replace the card with any new one.

There are 3 ranks in accordance to the color of the card frame. Green (Normal), Blue (Silver), Yellow (Gold), Source: RO2 website. Higher ranks card are obtainable through combining 5 cards of the same rank. Normal card can be obtatined fairly easy by usual farming, while Silver, and Gold, is just like the name suggest, really hard to obtain.
How to combine cards?
The synthetizing process can be done by going to Card Master [Card Merchant] NPC in every town, by choosing "Combine". Before you do so, make sure to have "Card Synthesis Stone" as it is required to start the synthetising process, you can buy the card synthesis stone at the Card Master by choosing "Item List" menu.
Prepare 5 different cards, talk to the npc and select "combine" option. Place 5 cards and stone inside. Press combine and pray hard it is successful as it has 50% of success rate only.
Results from combining cards
5 different cards combined together to produce a higher ranking. In regards to higher ranking, for example, 5 different normal card = 1 normal+ or 5 different normal card = 1 blue. The combination of 5 green cards may result in either normal + or blue.
Apparently, the card obtained from combination is one of the original 5 cards you used. The level of the card produced seems to be the card(used in combination) with the lowest level.Different input will affect its result.
How to replace cards?
Just drag a new card over the card you want to replace. Warning: Old card will be destroyed
Tips
In order to increase the rank of a card. The card must be from a monster higher than level 10. Visit any Card Merchant and you can upgrade a card. In order to do this, you must use 5 (five) different cards and place them in the wheel. (Order, AFAIK, is not important).
You must also have purchased a Card Synthesis Stone from the Card Merchant in order to Combine a Card. You may also purchase from the Cash Shop, a Card Designated Synthesis, which will allow you to specify which card you would like to be returned to you upgraded, in the event of a success.
Now for some math. With a 50% success rate and a 20% opportunity to get the card you want returned to you, it's safe to say that you have about a 10% chance of obtaining the card you want when you combine cards. The Card Designated Synthesis removes that 20% chance and makes it a 100% chance and thus giving you the original 50% chance back. (Does not garauntee a success still)
The other alternative would be to simply place 5 cards that you want to be upgraded and well... one of them has a 50% chance and the rest will disappear. There are many ways to go about combining cards.
Do not discard unusable cards. For example you are warrior and you got a card that boosts INT and WIS, do not discard or sell them. Use it for card synthesis, since the synthesis results will be random, there is a chance the a useful card for your class will shows up. If the + card stills of no use to you, auction it! Other people (or class) will find it useful and you can sell it on a much higher price than a “without +” card.
Only stores + card. Do not pile up normal cards as it will fill your storage/inventory up to it's limit in no time. If you get a useful card for your class, equip it, or else, synthesis it into a + card.
Do not invest money by buying cards unless you're on combat level 50, as in just a few hours/days you'll get much better cards on higher level.
