I haven't bought or rented any cards yet, are these cards good for the starting deck or would they change something?

What's the best elements and the cards to compose the best team of these elements?

What are the best quests in the game for you guys? I like sneak and snipe. Soon I will be posting my quests and matches in video and images, seeking to actually climb the rankings.

Good afternoon people! This game has helped me a lot and I hope to do the same for the community!
