I just got back into this game. As I see it, everything has changed a lot here ... I played somewhere in 2006. My request would be to help me make a solid deck, maybe even two. i have a lot of paradox clan cards as well as a bit of junkz. If someone has a desire and can help, write here or a letter
As Wyddyrshyns said arcade and solo/tutorial missions will also teach you the new abilities and clans. This will give you a better understanding of the game and the crypto coins will get you cr packs for either good cr cards or valuable ones that should let you have enough money to make multiple viable decks(with cards legal in all modes) easily
That Ld is not available in Arcade mode. Each of the Ld missions gives one random Ld that you don't have, so you'll have to go that route. Fortunately, the missions are far easier than they used to be.
