Why only the Dragon Knight and the Night Knight have survival cards in Kamen Rider Ryuki, but other knights don't?

The survival card is for Kamen Rider who has no clear goal and doesn't want to win, so that they can gain strength and fill them with desire. Such as Paul (Dragon Ride) and Osamu Tezuka (Hailei). Hailei gave him the night ride. There are only two survival cards.

Because dragon riding is the main knight, it is the ultimate form of dragon riding. Every black knight has the ultimate form, and the night riding is set as a famous auxiliary knight, so the power of the night riding is similar to that of the dragon riding. Dragon Ride is not only the power that every famous auxiliary knight in Kamen Rider will set as a full knight.

Cards owned by Kamen Rider Dragon Knight:

1, sealing card

You can seal the monster's card and force the monster not to attack the cardholder, but if the card is damaged or lost, the monster will attack the cardholder and eat it.

2. Contract card/arrival card

When a contract card is used to sign a contract with a monster in the mirror world, the card will display the symbol of the monster and become an arrival card. After that, the knight can borrow the power of the monster. The monster will not attack the contractor, but he will also be responsible for feeding the monster. The food of the monster is the core of other monsters after death. If you starve it for too long, the contract monster may eat the contractor.

Step 3 read cards

Inserting this card into the summoner can launch an attack, which contains stunts and weapons that the knight can use. When signing a contract with a monster, stunts and weapons will also be strengthened by the power of the monster. Finally, reading cards is the knight's biggest stunt (except the snake king).

4. Survival card

It was used by Shinzaki Shiro to become a knight but did not join the knight fight and stop the knight fight, bribing these knights' chips. * * * Three pieces, one of which was left to Masked Rider Odin and the other two were given to Kamen Rider Raia and Shinji Kido respectively. But in the end, there are only two survival cards, Xin Er and Lian.
