The stars at the top of the card represent possible Evolutions of the card. The one you mentioned is the 4*(star) card, which requires a minimum of 5 copies of the card to obtain.

To evolve a card, first you'll need two or more copies of the card. Go to the Upgrade screen and select the Evolution tab. Find the card you want to evolve and select the copy you want to fuse with it. When you combine two 0* cards, you'll get a 1* card. A 1* fused with a 0* will get you a 2* card. Keep combining 0* cards with your new card until you get the 4* card.

For cards you want to use in battle, you should max the level of both cards and use during evolution for each evolution step. Arcana succession can be found from Archwitch rewards, or bought in the shop for 100 Rare Medals. For amalgamations, max the level of all cards before amalgamating.

There are other ways to evolve 4* cards, but this should be enough to get you started. If you want to learn more about evolutions, you can check Evolution & Amalgamation. You can also check Upgrade for ways to max a card's level.
