I know that if you beat the guard armor it gives some king of points and if you get to 30,000 you get a riku sr card. but what about this cards? how can i get them? And how to get more points by fight?

I believe you get more points for fighting the guard armor variant (the gold one) and higher levels of the guard armor.

Though the cards in those pictures are new cards for the raise ticket and Kupo fruit/nut (I think google translate calls them fruit and some people call them nuts) card pool. So, if you can earn either of those from events, limited quests (the ones that disappear after x number of days), or buy them (with real money) you have a chance of getting some of those cards.
